Building a successful robotic-arm assisted orthopedic surgery program

Building a successful robotics team is a long journey with much effort before the first surgery. It starts with sound business development and, in case of acquiring a system, an implementation plan, to make it a success. The pathway to a successful Robotics program is much more than choosing the desired robotic arm-assisted surgery (RAS) brand. Success also depends on the specific pathway optimization aspects of RAS. High-over, all systems introduce the computer and robotic-arm into the operating room. But all systems have subtle, but significant, differences. An essential aspect of a successful RAS project is the implementation phase. After deciding to purchase a Robotic system, the following training and OR setup phase should be prepared and executed. When the robotic system enters the operating room, aspects like arm position using the arm board should be evaluated critically since the robot needs sufficient working space. A suboptimal positioning will disrupt the team dynamics and lead to preventable delay. RAS requires new or adjusted skills. Two crucial aspects are eye-hand-feet coordination in combination with a different focus of the surgeon (also screen instead of 100% surgery field) and new cognitive decision making features. Robotic surgery is a perfect example of how technology can change a surgical field. This data acquisition is probably the most fundamental, powerful aspect of adding the computer into the surgical process. The most used robotic-arm systems in hip and knee arthroplasty are semi-automatic systems, and practically all major orthopedic manufacturers offer a device. ORs are a highly capitalized section of hospitals, generating high costs and critical revenues. Therefore, taking a closer look at workflows, inventory management, and team efficiencies is crucial. Improving these aspects in the OR has a high return on investment. RAS helps accurately observe everything occurring within and around the surgical process. These new data opportunities open the opportunity to work with surgical data science (SDS).

DISPLACED SUPRACONDYLAR HUMERUS FRACTURES REDUCED WITH CLOSED REDUCTION AND PERCUTANEOUS PINNING USING THE ARM BOARD TECHNIQUE IN CHILDREN.

Introduction: Closed reduction percutaneous pinning is the current gold standard of treatment for displaced supracondylar fractures of the humerus in children (CRPP). A simple CRPP process using a radiolucent arm board and simpler C-arm handling is described in this methodology. This method yields reproducible results and is easy to copy. It may also be used to any standard operating table.

Lateral Decubitus Positioning For Shoulder Arthroscopy

Background: Lateral decubitus positioning is a frequently employed technique to perform shoulder arthroscopy. Proper patient positioning and equipment setup is crucial to ensure a safe and efficient surgery. Indications: The common indications for performing a shoulder arthroscopy in the lateral decubitus position include anterior shoulder stabilization, posterior shoulder stabilization, superior labrum anterior to posterior (SLAP) repair, diagnostic arthroscopy for internal impingement, and arthroscopic capsular release for adhesive capsulitis. Technique Description: After undergoing general endotracheal anesthesia in the supine position on a standard operating room table, the patient is rotated into the lateral decubitus position with the operative arm facing upward. The patient’s head is supported with a pillow to ensure a neutral position. The nonoperative arm is flexed forward and rests on a padded arm board. The sides of a bean bag are applied to the patient’s torso to maintain the lateral decubitus position, and the bean bag is deflated to remain rigid. An axillary roll is placed under the axilla, and foam pads are placed below the “down leg” and between both legs. A commercial arm jack is positioned on the anterior, proximal side of the operating room table to allow for 20° of shoulder abduction, which maximizes the glenohumeral joint space. Results: Advantages of the lateral decubitus position over the beach chair position include improved access to the anterior, inferior, and posterior glenoid; more ergonomic positioning for the operating surgeon; lower risk for patient cerebral hypoperfusion; and reduced rates of recurrent instability following arthroscopic stabilization in comparison to procedures performed in the beach chair position. Disadvantages of the lateral decubitus position include risk of traction-related neurovascular injury, requirement of an arm suspension device, and increased difficulty in rotating the shoulder intraoperatively. Discussion/Conclusion: Lateral decubitus positioning is commonly used to achieve a circumferential view of the glenohumeral joint in shoulder arthroscopy. This surgical position yields several advantages for the operating surgeon and has been shown to be associated with improved clinical outcomes after shoulder instability surgery.

Minimizing Surgeon Radiation Exposure During Operative Treatment of Pediatric Supracondylar Humerus Fractures.

Orthopaedic surgeons are exposed to high levels of radiation, which may lead to higher rates of cancer among orthopaedic surgeons. There are a series of techniques currently practiced to pin supracondylar humerus fractures including pinning the arm on the C-arm itself, using a plexiglass rectangle or a graphite floating arm board; however, the variation in radiation exposure to the surgeon is unknown. We aimed to determine how the position of the C-arm affects radiation exposure to the surgeon during the treatment of a pediatric supracondylar humerus fracture. A simulated operating room was created to simulate a closed reduction and percutaneous pinning of a supracondylar humerus fracture. A phantom model was used to simulate the patient's arm. We assessed performing the procedure with the arm on plexiglass, graphite, or on top of the C-arm image receptor. The C-arm was positioned either with the source down and image receptor up (standard position) or with the source up and image receptor down (inverted position). Radiation exposure was recorded from levels corresponding to the surgeon's head, midline, and groin. The estimated effective dose equivalent was calculated to account for the varying radiation sensitivity of different organs. We found the effective dose equivalent, or the overall body damage from radiation, was 5.4 to 7.8% higher than the surgeon when the C-arm was in the inverted position (source up, image receptor down). We did not find any differences in radiation exposure to the surgeon when the arm was supported on plexiglass versus graphite. The C-arm positioned in the standard fashion exposes the surgeon to less damaging radiation. Therefore, when the surgeon is standing, we recommend using the C-arm in the standard position. Orthopaedic surgeons who stand should use the C-arm in the standard position to pin supracondylar humerus fractures to lower the risk of ionizing radiation exposure.

The Hand Hug: A Novel Test for Linburg-Comstock Syndrome and Wide-awake Correction of the Anomaly.

In 1979, Linburg and Comstock1 described an inability to flex the interphalangeal joint of the thumb without simultaneously flexing the distal interphalangeal joint of the index finger, caused by a congenital anomalous connection between the flexor pollicis longus tendon and the flexor digitorum profundus tendon to the index finger. The “hand hug test” is a novel clinical test for this condition. The palm of the affected hand of the patient is placed on the ipsilateral palm of the examiner’s hand with all the digits lined up in extension. The thumbs are abducted. The patient is asked to bend the thumb around the examiner’s hand while the examiner does the same action—as if the hands are “hugging.” Because the index finger of the patient and the small finger of the examiner are aligned and blocking each other in extension, the thumb of the patient with the Linburg-Comstock anomaly is not able to make a “hand hug.” We report the case of a 20-year-old, right-hand dominant carpentry student who had a complete inability to move his right thumb and right index finger independently. The patient did have the anomaly on the contralateral side, but it was far less pronounced. Specific activities affected by the anomaly were piano, typing, and rock climbing. The phenomenon had always been present but was progressively becoming more pronounced, with no clear history of an inciting traumatic event. We performed a point-of-care ultrasound examination and observed a pathologic band in both the coronal and sagittal view, which was 4 cm in length. We agree that magnetic resonance imaging or computed tomography scan can be helpful to characterize the anatomy, but high-frequency ultrasonography is sufficient to localize the congenital band.2 We performed wide-awake surgery with subcutaneous local anesthesia infiltration of 10 mL lidocaine 1% with 10 mg/mL of epinephrine with 20 mL saline buffered with 2 mL 8.3% bicarbonate [wide awake local anesthesia no tourniquet (WALANT) technique].3 The local anesthesia was allowed at least 45 minutes to take effect before the procedure. The patient was positioned supine with the affected limb on an arm board without a tourniquet. The surgical field was prepared and draped using field sterility. A linear incision was made along the radial aspect of the distal forearm over the flexor carpi radialis tendon, just proximal to the volar wrist crease. The anomalous connection was confirmed by the synkinesis of the tendons on both active and passive intraoperative testing. We observed the fibrous type anomalous connection, which is the most common type among the classification of Yurasakpong et al.4 We sharply divided the connection, which immediately corrected the anomaly. The thumb and index finger could now move independently, and the patient was able to make the “hand hug” with the surgeon [See Video (online), which displays the preoperative clinical and ultrasound examination, surgical procedure, and final result with the “hand hug test” for each step]. The patient was mobilized immediately, using principles of hand elevation, early cessation of postoperative analgesics, and “pain-guided healing.” Hand therapy was used to encourage independent tendon gliding. He made a complete recovery and was able to return to normal activities without restrictions. {"href":"Single Video Player","role":"media-player-id","content-type":"play-in-place","position":"float","orientation":"portrait","label":"Video 1.","caption":"This video displays the preoperative clinical and ultrasound examination, surgical procedure and final result with the « hand hug test” for each step.","object-id":[{"pub-id-type":"doi","id":""},{"pub-id-type":"other","content-type":"media-stream-id","id":"1_pcsm1wze"},{"pub-id-type":"other","content-type":"media-source","id":"Kaltura"}]} PATIENT CONSENT The patient provided written consent for the use of his image.

Battery Management System to Estimate Battery Aging using Deep Learning and Machine Learning Algorithms

One of the greatest challenges faced by Electric Vehicle (EV) manufactures is insufficient charging stations. Estimating the aging of the battery in the electric vehicle helps the driver to predict the driving range of the vehicle. This paper proposes a battery management system that is developed to predict remaining battery charge of the Electric Vehicle. The aging of the lithium-ion (Li-Ion) battery present in the electric vehicle is predicted using different machine learning and deep learning algorithms. The parameters such as voltage, current and temperature are taken from the sensors connected to the LPC2148 ARM board and the values are given as dataset to the Long Short-Term Memory (LSTM), Decision Tree (DT), K-Nearest Neighbors (KNN), Naïve Bayes (NB) and Support Vector Machine (SVM) Algorithms. The experimental results indicate that for real-time data Naïve Bayes algorithm gave the best results in terms of metrics such as Accuracy, Precision, Recall and F1-score. Naïve Bayes produced results with the accuracy rate of 88% and used to calculate the Remaining Battery Capacity which helps predicting the aging of the lithium- ion battery.

An intelligent fast controller for autonomous wheeled robot path navigation in challenging environments

PurposeThis paper aims to incorporate one intelligent particle swarm optimization (IPSO) controller to realize an optimum path in unknown environments. In this paper, the fitness function of IPSO is designed with intelligent design parameters, solving the path navigation problem of an autonomous wheeled robot towards the target point by avoiding obstacles in any unknown environment.Design/methodology/approachThis controller depends on randomly oriented positions with all other position information and a fitness function. Evaluating the position’s best values, this study gets the local best values, and finally, the global best value is updated as the current value after comparing the local best values.FindingsThe path navigation of the proposed controller has been compared with particle swarm optimization algorithm, BAT algorithm, flower pollination algorithm, invasive weed algorithm and genetic algorithm in multiple challenging environments. The proposed controller shows the percent deviation in path length near 14.54% and the percent deviation in travel time near 4% after the simulation. IPSO is applied to optimize said parameters for path navigation of the wheeled robot in different simulation environments.Originality/valueA hardware model with a 32-bit ARM board interfaced with a global positioning system (GPS) module, an ultrasonic module and ZigBee wireless communication module is designed to implement IPSO. In real-time, the IPSO controller shows the percent deviation in path length near 9%.

Robot-assisted nephroureterectomy requiring no robot redocking or patient repositioning: experience from a single center with 62 cases

Objective: To examine a new technique of robot-assisted nephroureterectomy without robot reldocking or patient repositioning. Methods: Patients diagnosed as upper tract urothelial carcinoma treated with this modality between November 2015 and January 2019 at Department of Urology, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine were included in this analysis. Data collection including patient demographics, operative procedure and postoperative morbidities were conducted by retrospective charts review, after receiving the institutional review board's approval. There were 35 males and 27 females with a median age of 70 years (range: 30 to 91 years) underwent single docking robot-assisted nephroureterectomy without repositioning. Among the 62 cases, 37 patients had pelvic carcinoma while 25 patients had ureteral carcinoma (with proximal portion 12 cases, middle portion 5 cases and distal portion 8 cases). The patient was placed in a 60 to 80-degree, modified flank position with a 15-degree Trendelenburg tilt. The contralateral arm was positioned perpendicular to the torso on an arm board while the ipsilateral arm was taped to the patient's side with ample padding. The robot cart was then docked at a 90-degree angle, perpendicular to the patient. A "W"-shape, three robotic-arm configurations was used for port placement. Results: The surgical procedures were performed successfully in all the 62 patients. The operation time was (171.6±54.7) minutes (range: 60 to 370 minutes). The estimated blood loss during the operation was 50(50) ml (range: 20 to 400 ml) with 4 patients had transfusion. No perioperative death was encountered. Eleven patients had post-operative complications (Clavien-Dindo grade 2) including 3 cases of hemorrhage and 8 cases of chylous leakage. All cases were regularly followed up with a median time of 37 months (range: 17 to 55 months). There were 8, 30, 19, 4 and 1 case followed up for 48, 36, 24, 18 and less than 18 months, respectively. Three patients had reginal recurrences and 11 cases of distant metastasis occurred, with 5 patients died for cancer. The survival rate within 24 months was estimated as 75.4%(43/57). Conclusion: Robot-assisted nephroureterectomy without robot redocking or patient repositioning could be safely reproduced, with surgical outcomes comparable to other established techniques.

Open Reduction and Internal Fixation of Pediatric Medial Epicondylar Humeral Fractures in the Prone Position.

Fracture of the medial epicondyle is a common pediatric injury, with an estimated annual incidence of 40 to 60 per 100,000 people per year1-3. Medial epicondylar fractures are associated with elbow dislocation in about 60% of cases, and ulnar nerve dysfunction is reported to occur nearly 10% of the time2,4. No standard of care for medial epicondylar fracture exists, as similar outcomes have been demonstrated in observational studies with both operative and nonoperative treatment5,6. Increasingly, however, these injuries are being treated with surgical intervention, which in most cases consists of a single screw affixing the osseous piece back to its donor site on the humerus7-9. There is broad consensus on the absolute indications for operative treatment, including an open fracture and an incarcerated epicondylar fragment1,10-13. The relative indications are more controversial and include ulnar nerve dysfunction, elbow instability, increased fragment displacement, and high-level throwing or upper-extremity weight-bearing athletes2,9,14-16. The patient is placed in the prone position with the operative arm on a radiolucent arm board. A milking maneuver with an Esmarch bandage is utilized. A posteromedial incision is made over the medial epicondyle. The ulnar nerve is protected posteriorly. The fracture is easily reduced under minimal tension, and then 1 or 2 guidewires from the 4.0-mm cannulated screw kit are placed to fix the fragment. The central guidewire is overreamed, and then a partially threaded 4.0-mm screw is placed in a relative posterior-to-anterior trajectory within the medial column of the elbow. Nonoperative treatment includes immobilization in a long arm cast until fragment healing. Complications associated with nonoperative treatment include nonunion and late instability. Supine positioning is a reasonable alternative to the prone position described here. In that case, the fracture is fixed with the arm in external rotation of the shoulder and with the elbow extended. Prone positioning for operative treatment of medial epicondylar fractures is preferred because the tension from the flexor pronator mass associated with supine positioning is negated, facilitating an easier fracture reduction and improved anatomic reduction. To our knowledge, there are currently no Level-I or Level-II prospective studies reporting on the outcomes of operative versus nonoperative treatment of medial epicondylar fractures. A systematic review of retrospective results suggested no difference in pain or clinical outcomes, but >9-times greater odds of union with operative treatment5,6. Expectations following operative treatment of a medial epicondylar fracture have been explored in multiple studies. Generally, return to full levels of activity and near-normal range of motion of the elbow have been demonstrated by most. Minor rates of range-of-motion limitation, including extension deficit (4% with deficit up to 20°) are reported in some studies8. In the setting of preoperative instability, the expectation is that elbow stability will be achieved by operative treatment7,8. Perform and document an accurate preoperative neurovascular examination of the arm.Test the shoulder in internal rotation prior to prone positioning.Protect the ulnar nerve during surgical fixation and drilling.Confirm that the screw trajectory is relatively posterior to anterior and only in the medial column of the elbow.

Insertion, management, and complications associated with arterial catheters in paediatric intensive care: A clinical audit

IntroductionPeripheral arterial catheters (PAC) are used for haemodynamic monitoring and blood sampling in paediatric critical care. Limited data are available regarding PAC insertion and management practices, and how they relate to device function and failure. This information is necessary to inform future interventional research. ObjectivesThe primary objective of this study was to describe PAC insertion and management practices, and associated complications. Secondary objectives were to determine patient and clinical characteristics associated with risk of PAC successful insertion and failure. MethodsA prospective, observational study was conducted in the anaesthetic department and paediatric intensive care unit of a tertiary paediatric facility. Data were collected on PAC insertion, PAC management and PAC removal. Standard incidence and prevalence were calculated per 1,000 device days. Risk factors for multiple insertions and PAC failure were identified using Cox regression. ResultsA total of 100 catheters in 89 children were examined capturing 472 device days. PACs were primarily inserted for blood sampling (78%) in the radial artery (78%) using ultrasound guidance (67%), with 31% inserted on first attempt. Heparin saline solution was used in 82% of devices. Median catheter dwell was 50.6 hours (IQR 24.0 – 158.0), with PAC failure occurring in 19 devices (20%), at a rate of 40.2 per 1000 catheter days (95% CI 25.7 - 63.1). Arm board immobilisation (HR 2.9; 95% CI 1.02-8.02; p = 0.05), higher PIM3 score (HR 1.06; 95% CI 1.03-1.09; p < 0.01) was associated with an increased the risk of PAC failure, and non-2% chlorhexidine antisepsis was associated with a decrease in PAC failure (HR 0.32; 95% CI 0.11-0.96; p = 0.04), in univariate analysis. ConclusionsPAC insertion is challenging, and failure is common. Prospective clinical trial data is needed to identify high risk patient groups and to develop interventions which optimise practices, thereby reducing failure.

Rapid Control Prototyping based on 32-Bit ARM Cortex-M3 Microcontroller for Photovoltaic MPPT Algorithms

Since the beginning of the war in Syria, most of the electricity infrastructure has been destroyed, leaving millions with unreliable energy. Syrians have encountered high electricity production costs and environmental damage costs resulting from the utilization of fossil fuels. Similarly, Syria has abundant solar energy can be exploited to meet its electrical power needs. However, because of a lack of expertise in solar energy conversion and the high cost of smart technology, Syrians have typically used photovoltaic systems in primitive ways, in which the efficiency of solar energy conversion is low. There is, therefore, a need for inexpensive, easy-to-implement, yet highly efficient and high performing solutions. Using the STMicroelectronics 32-bit ARM as a maximum power point tracking (MPPT) controller offers a potential solution to the problem of low conversion efficiency in standalone solar systems. In this study, using Matlab-Simulink and STMicrelectronics-32 bit ARM board, simulation and practical test is set up to evaluate the performance of the Perturbation & Observation, Incremental Conductance and Fuzzy Logic MPPT algorithms, in order to determine the most appropriate algorithm to use in small scale solar energy systems. Therefore, one main objective of this study is to explore rapid control prototyping tools for saving time and effort to the experts in the implementation process of the proposed systems. The results indicate the effectiveness of Fuzzy logic algorithm to draw more energy, decrease oscillation and provide a fast response under variable weather conditions. Furthermore, the three algorithms were able to find and track MPP.

The two-frame images are captured continuously by vertically shooting the camera, and the strong angle points are used to track the velocity information. This design takes the ARM board of Banana PI (BPI-M2 Ultra) as the core, combines the processing of OpenCv visual function library, extracts and tracks the feature points by using the strong angle extraction algorithm, and uses the pyramid Lucas-Kanade optical flow method can track the feature points. The tracking of the characteristic point information is tracked to remove the distorted displacement information and calculate the velocity information using the relationship of the frame rate displacement.

Touch fingerprint sensor based on sensor cell isolation technique with pseudo direct signaling

Abstract This paper presents a 96 × 96 fingerprint sensor implemented with 0.25 μm standard CMOS technology. The implemented fingerprint sensor is based on a pseudo-direct signaling scheme that does not require an electrode for signal transmission. And the pseudo-direct signaling was combined with sensor cell isolation scheme which controls the unwanted influx of the electric fields effectively. And a pipelined scan technique was applied for fast fingerprint image capture while maintaining SNR performance. It was fabricated with 0.25 μm standard CMOS technology and was molded with 80 μm-thick epoxy after fabrication. The fingerprint sensor was tested with ARM board combined with PC applications. The obtained fingerprint images from the fingerprint sensor were enhanced to reduce the noise of the obtained images by using filtering technique, such as Wiener, 2D Gaussian, and 2D FIR filtering. From the test results, it was concluded that the implemented fingerprint sensor with the isolation scheme worked well without bezel electrode and can be used in biometric authentication systems effectively.

Remote measurement of low-energy radiation based on ARM board and ZigBee wireless communication

We propose a system for remote measurement of low-energy radiation, which is implemented using an ARM board and a ZigBee module. The ARM STM32F103 board employs a horizontal and vertical moving CMOS camera for front-end data acquisition. The camera can detect radiation over different coordinates given by latitude and longitude in a determined area. For image processing, we used the subtraction–summation algorithm based on gradient multiplication and edge detection. Compared to algorithms such as the max grayscale value, subtraction–summation, and whole summation, the improved subtraction–summation algorithm filters noise and removes the background grayscale value of the whole image to attain higher accuracy, stronger anti-interference ability, and better consistency to determine the radiation dose. We dedicated one port of the transmission module to send data through the STM32F103 board, whereas another port is connected to the ZigBee module for data reception. By employing this architecture, we achieved low power consumption and fast response in the remote data transmission. Overall, the proposed system performs the remote measurement of low-energy radiation with stability and reliability, which is required for critical scenarios such as the remote detection of nuclear radiation.

Cone-beam CT acquisition during transradial TACE made easy; use of the swivel arm board.

Transradial access for peripheral intervention often requires certain modification from its coronary counterparts. One of the challenges during transradial transarterial chemoembolization (TACE) is the need for the access arm to be repositioned during cone-beam CT (CBCT) acquisition to allow for C-arm rotation. We recently introduced a swivel arm board to allow seamless repositioning of the access arm during and after CBCT acquisition. The purpose of this study is to detail the technique and feasibility of this useful adjunct to transradial TACE. We performed a retrospective study of consecutive cases of transradial TACE between November 2015 and March 2016, which represented the period where we introduced the swivel arm board to our transradial procedure. A total of 20 transradial TACE using the swivel arm board was performed in 17 patients. There were 13 males and 4 females. The mean age was 69.5 years old (range 48-82 years). Indications for TACE included hepatocellular carcinoma (n = 14) and metastatic liver disease (n = 3). Transradial TACE was successful in all cases. A total of 40 successful arm repositioning using the swivel arm board for CBCT acquisitions were performed (100% success rate). There was no catheter or sheath dislodgement associated with the arm movements. No change in the microcatheter tip position was detected as a result of the arm repositioning. Hemostasis was successfully achieved in all the patients. There was no access related complication. The swivel arm board is a useful adjunct to enable CBCT acquisition during transradial TACE. Advances in knowledge: Transradial TACE is a novel technique, and adaptation to allow for CBCT acquisition is currently challenging. This manuscript illustrates how to overcome the positioning difficulties with the use of the swivel arm board.

The AXIOM software layers

People and objects will soon share the same digital network for information exchange in a world named as the age of the cyber-physical systems. The general expectation is that people and systems will interact in real-time. This poses pressure onto systems design to support increasing demands on computational power, while keeping a low power envelop. Additionally, modular scaling and easy programmability are also important to ensure these systems to become widespread. The whole set of expectations impose scientific and technological challenges that need to be properly addressed.The AXIOM project (Agile, eXtensible, fast I/O Module) will research new hardware/software architectures for cyber-physical systems to meet such expectations. The technical approach aims at solving fundamental problems to enable easy programmability of heterogeneous multi-core multi-board systems. AXIOM proposes the use of the task-based OmpSs programming model, leveraging low-level communication interfaces provided by the hardware. Modular scalability will be possible thanks to a fast interconnect embedded into each module. To this aim, an innovative ARM and FPGA-based board will be designed, with enhanced capabilities for interfacing with the physical world. Its effectiveness will be demonstrated with key scenarios such as Smart Video-Surveillance and Smart Living/Home (domotics).

The use of graphene-based earphones in wireless communication

Graphene-based materials have attracted much attention in recent years. Many researchers have demonstrated prototypes using graphene-based materials, but few specific applications have appeared. Graphene-based acoustic devices have become a popular topic. This paper describes a novel method to fabricate graphene-based earphones by laser scribing. The earphones have been used in wireless communication systems. A wireless communication system was built based on an ARM board. Voice from a mobile phone was transmitted to a graphene-based earphone. The output sound had a similar wave envelope to that of the input; some differences were introduced by the DC bias added to the driving circuit of the graphene-based earphone. The graphene-based earphone was demonstrated to have a great potential in wireless communication.
