Drop-on-demand (DOD) inkjet dynamics of printing viscoelastic conductive ink

Emerging applications of drop-on-demand (DOD) inkjet printing, such as printed electronics and bioprinting, are leading to an ever-increasing development of diverse functional inks with complex chemical and rheological properties, especially viscoelastic polymers. Forming droplets with desirable velocity and volume as well as excellent reliability is of great importance for successful printing. In this study, the dynamics and performance of droplet formation during DOD inkjet printing of viscoelastic ink were investigated by employing the piezoelectric inkjet technology to print a conductive polymer ink under various excitation waveform parameters. Four distinct droplet formation regimes were identified, namely, no droplet formation, a single droplet, one satellite droplet, and multiple satellite droplets. A process dynamics-related dimensionless number (Wj) was proposed to construct an operating phase diagram on droplet formation and quantify the transition of droplet formation regimes. The effects of bipolar waveform parameters on droplet formation were systematically examined in terms of Wj, droplet velocity, and droplet diameter. Moreover, the printing of conductive microlines and micropatterns was precisely controlled under well-formed droplets. This study could support fully understanding the droplet formation dynamics during DOD inkjet printing of viscoelastic inks to guide generating desirable droplets of functional ink and improve the performance and function of inkjet-printed devices.

Harvesting energy from vehicle transportation on highways using piezoelectric and thermoelectric technologies

For many years, the rate of energy consumption has been higher than the rate at which natural resources are being generated. Green energy is a major solution to achieve a sustainable future and mitigate carbon footprints. Today, the transport sector highly relies on fossil fuel, consuming nearly one-quarter of the total energy in developed countries and represents a massive environmental burden. Hence, the fate of future energy security does not solely lie in the efficient use of existing green energies but also in the development of new energy sources. This study proposed the design of thermoelectric and piezoelectric energy harvesting systems to make use of the huge thermal energy due to solar radiation and mechanical strain due to moving vehicles to generate electricity. Both systems were built at an experimental scale model and tested. The thermoelectric system produced an output power of 1.06 mW and an open-circuit voltage of 118.2 mV at a temperature difference of 14.8 °C. A maximum average power output of 1.55 mW is achieved over a period of 6h per day. The Piezoelectric generated a peak DC voltage of 9.83 V, under normal stress of 235.04 kPa. The results also showed that the piezoelectric system could provide a consistent output voltage as long as the system experience normal stress. The system could produce an output power of 0.2 mW.

Development and performance analysis of hemispherical piezoelectric transducer for road applications

Following the extensive research on piezoelectric technology and the increasing popularity of intelligent transportation during the past few years, the harvesting of pavement vibration energy has attracted increased research attention. At present, most innovations in the direction of the road piezoelectric energy are focused on the materials and structures of the transducers. However, few transducers meet the road requirements. Therefore, in this study, a hemispherical piezoelectric transducer was developed for road applications. We also analyzed the effects of different sizes and structures of transducers on energy harvesting efficiency based on laboratory tests, and the outcomes were compared with those from plane transducers. Under the excitation frequency of 10 Hz and the load of 0.7 MPa, the maximum output power of the planar transducer was 0.422 mW, while the power of the hemispherical transducer at the same load was 0.765 mW. Based on the dynamic load test, the ultimate load of the hemispheric transducer was 1900 N, which was 2.66 times that under standard axial load. Subsequently, a dynamic fatigue test was conducted for 24 h at the excitation conditions of 10 Hz and 0.7 MPa, wherein the voltage attenuation of the plane transducer exceeded 60%, while that of the hemispheric transducer was <20%. The experimental results show that the structure had a stable performance and good durability, and its strength and acquisition efficiency met the requirements of road transducers.

A PZT-based electromechanical impedance method for monitoring the moisture content of wood

PurposeAt present, piezoelectric impedance technology has been used in the study of wood damage monitoring. However, little effort has been made in the research on the application of piezoelectric impedance system to monitor the change of wood moisture content (MC). The monitoring method of wood MC is used by piezoelectric impedance technique in this study.Design/methodology/approachOne piezoceramic transducer is bonded to the surface of wood specimens. The MC of the wood specimens increases gradually from 0% to 60% with 10% increments; the mechanical impedance of the wood specimen will change, and the change in the mechanical impedance of the structure is reflected by monitoring the change in the electrical impedance of lead zirconate titanate. Therefore, this paper investigates the relationship between wood MC change and piezoelectric impedance change to verify the feasibility of the piezoelectric impedance method for monitoring wood MC change.FindingsThe experiment verified that the real part of impedance of the wood increased with the increase of wood MC. Besides, the damage index root mean square deviation is introduced to quantify the damage degree of wood under different MC. At the same time, the feasibility and validity of this experiment were verified from the side by finite element simulation. Finally, MC monitoring by piezoelectric impedance technique is feasible.Originality/valueTo the best of the authors’ knowledge, this work is the first to apply piezoelectric ceramics to the monitoring of wood MC, which provides a theoretical basis for the follow-up study of a wide range of wood components and even wood structure MC changes.

A Piezoelectric Ionic Cocrystal of Glycine and Sulfamic Acid.

Cocrystallization of two or more molecular compounds can dramatically change the physicochemical properties of a functional molecule without the need for chemical modification. For example, coformers can enhance the mechanical stability, processability, and solubility of pharmaceutical compounds to enable better medicines. Here, we demonstrate that amino acid cocrystals can enhance functional electromechanical properties in simple, sustainable materials as exemplified by glycine and sulfamic acid. These coformers crystallize independently in centrosymmetric space groups when they are grown as single-component crystals but form a noncentrosymmetric, electromechanically active ionic cocrystal when they are crystallized together. The piezoelectricity of the cocrystal is characterized using techniques tailored to overcome the challenges associated with measuring the electromechanical properties of soft (organic) crystals. The piezoelectric tensor of the cocrystal is mapped using density functional theory (DFT) computer models, and the predicted single-crystal longitudinal response of 2 pC/N is verified using second-harmonic generation (SHG) and piezoresponse force microscopy (PFM). The experimental measurements are facilitated by polycrystalline film growth that allows for macroscopic and nanoscale quantification of the longitudinal out-of-plane response, which is in the range exploited in piezoelectric technologies made from quartz, aluminum nitride, and zinc oxide. The large-area polycrystalline film retains a damped response of ≥0.2 pC/N, indicating the potential for application of such inexpensive and eco-friendly amino acid–based cocrystal coatings in, for example, autonomous ambient-powered devices in edge computing.

Self-Powered Sensors: New Opportunities and Challenges from Two-Dimensional Nanomaterials.

Nanomaterials have gained considerable attention over the last decade, finding applications in emerging fields such as wearable sensors, biomedical care, and implantable electronics. However, these applications require miniaturization operating with extremely low power levels to conveniently sense various signals anytime, anywhere, and show the information in various ways. From this perspective, a crucial field is technologies that can harvest energy from the environment as sustainable, self-sufficient, self-powered sensors. Here we revisit recent advances in various self-powered sensors: optical, chemical, biological, medical, and gas. A timely overview is provided of unconventional nanomaterial sensors operated by self-sufficient energy, focusing on the energy source classification and comparisons of studies including self-powered photovoltaic, piezoelectric, triboelectric, and thermoelectric technology. Integration of these self-operating systems and new applications for neuromorphic sensors are also reviewed. Furthermore, this review discusses opportunities and challenges from self-powered nanomaterial sensors with respect to their energy harvesting principles and sensing applications.

Silicon‐Photonics Point Sensor for High‐Resolution Optoacoustic Imaging

AbstractThe recent development of ultrasound sensing using the silicon‐photonics platform has enabled super‐resolution optoacoustic imaging not possible by piezoelectric technology or polymeric optical microresonators. The silicon waveguide etalon detector (SWED) design exploits the sub‐micrometer light confinement in the cross‐section of a silicon strip waveguide to achieve a sensor aperture which is 13‐fold to 30‐fold smaller than the cutoff wavelength of the sensor. While its performance in near‐field scanning optoacoustic imaging has been previously studied, the operational characteristics of this sensor as it relates to conventional optoacoustic imaging applications are not known. Here, for the first time, the application of the SWED in optoacoustic mesoscopy is investigated, the interaction of the sensor with ultrasound in the far‐field is characterized, the acoustic point spread function up to a depth of 10 mm is measured, and 3D vasculature‐mimicking phantoms are imaged. The measured point spread function of the sensor shows that surface acoustic waves can degrade the lateral resolution. Nevertheless, superior resolution is demonstrated over any state‐of‐the‐art ultrasound sensor, over the whole range of imaging depths that are of interest to optoacoustic mesoscopy. Silicon photonics is proposed as a powerful and promising new platform for ultrasonics and optoacoustics.

Formation of 3D Self-Organized Neuron-Glial Interface Derived from Neural Stem Cells via Mechano-Electrical Stimulation.

Due to dissimilarities in genetics and metabolism, current animal models cannot accurately depict human neurological diseases. To develop patient-specific in vitro neural models, a functional material-based technology that offers multi-potent stimuli for enhanced neural tissue development is devised. An electrospun piezoelectric poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) nanofibrous scaffold is systematically optimized to maximize its piezoelectric properties while accommodating the cellular behaviors of neural stem cells. Hydro-acoustic actuation is elegantly utilized to remotely activate the piezoelectric effect of P(VDF-TrFE) scaffolds in a physiologically-safe manner for the generation of cell-relevant electric potentials. This mechano-electrical stimulation, which arose from the deflection of the scaffold and its consequent generation of electric charges on the scaffold surface under hydro-acoustic actuation, induces the multi-phenotypic differentiation of neural stem cells simultaneously toward neuronal, oligodendrocytic, and astrocytic phenotypes. As compared to the traditional biochemically-mediated differentiation, the 3D neuron-glial interface induced by the mechano-electrical stimulation results in enhanced interactions among cellular components, leading to superior neural connectivity and functionality. These results demonstrate the potential of piezoelectric material-based technology for developing functional neural tissues in vitro via effective neural stem cell modulation with multi-faceted regenerative stimuli.

Design and testing of road piezoelectric power generation device based on traffic environment applicability

This paper presents a design scheme for the applicability of piezoelectric power generation device in road traffic environment, which overcomes the problem of limited application due to the existing technology inapplicability to the complicated and changeable road traffic environment. Then, the traffic environment applicability of the device is evaluated with respect to the traffic load, temperature and water. And the electrical output effects are tested under different loads. The results indicate that under the load of 2.86 times the standard traffic load, the overall deformation of the device is only 0.941 mm, and the device exhibits good compression stability. The maximum internal temperature change rate of the device under different ambient temperatures is 2.4 °C/h, which is far lower than the pavement. Furthermore, the weight of the device increases by only 2.1 g after 24 h of immersion in water, with no moisture inside the device. Therefore, the device has excellent applicability in the traffic environment. Finally, the voltage and power of the device under the 0.9 MPa – 5 Hz can reach 96 V and 43.264 mW, and the power density reaches 0.064 mW/cm3, which is much higher than existing devices. This work will promote the application of piezoelectric energy harvesting technology in road engineering.

A high density piezoelectric energy harvesting device from highway traffic — System design and road test

Massive dissipated kinetic energy of roadway traffic is a sustainable energy source that can be harvested via piezoelectric effect. The piezoelectric energy harvesting technology provides a robust and reliable solution of roadway power generation. However, it remains challenging to achieve high energy density in order for the harvested energy to be of utility value. Here, we demonstrate an innovative roadway piezoelectric energy harvesting system, which reaches an energy density as high as 15.37 J/(m.pass.lane) based on the open-circuit voltage measurements in road tests. The high energy density is achieved by incorporating a compression-to-compression force amplification mechanism as well as an optimized system configuration to take full advantage of dynamic load from vehicles. To the best of our knowledge, the prototype system has achieved the highest energy density reported in the literature, and holds the great potential to be part of the smart highway.

Analysis of the Vibration Suppression of Double-Beam System via Nonlinear Switching Piezoelectric Network

In this paper, a method to suppress the vibration of a double-beam system with nonlinear synchronized switch damping on the inductor via a network (SSDI-net) is proposed. Unlike the classical linear piezoelectric shunt damping, SSDI-net is a nonlinear piezoelectric damping. A double-beam system with SSDI-net was simplified to a lumped parameter electromechanical coupling model and analyzed by using the multi-harmonic balance method, at first with alternating frequency–time techniques (MHBM/AFT). Then, a new lower-power autonomous switching control circuit board was designed, based on SSD technique, and vibration control experiments using a double-beam system with an SSDI network are conducted, to verify the validity of the proposed analysis method and its calculation results. The nonlinear switching piezoelectric network proposed in this article can increase the voltage inversion factor. Furthermore, future applications of this switching piezoelectric network technology in the vibration suppression of bladed-disk structures in aero engines can reduce the number of switches by at least half and obtain almost the same damping effect.

Research on multi-group dual piezoelectric energy harvester driven by inertial wheel with magnet coupling and plucking

Piezoelectric technology has attracted extensive attention and played an increasingly important role in the aspect of harvesting energy from the environment, which has advantages of simple structure, good performance, and so on. In this study, a multi-group dual piezoelectric energy harvester driven by inertial wheel with magnet coupling and plucking (M−PEH) is proposed. The M−PEH mainly includes a base, supports, piezoelectric patches, magnets, magnets cover, and rotor. This paper studies the series–parallel connection relationship between the circular and rectangular piezoelectric patches in the circumferential direction of the base, and the influence on the peak-to peak voltage when the length of the magnet extending from the surface of the rotor is different. Under the condition of inertial wheel 407 g, the M−PEH is tested and researched from 50 r/min to 600 r/min. After a series of experimental studies at 550 r/min, the peak-to-peak voltages of the circular and rectangular piezoelectric patches are respectively 15.00 V, 28.74 V, and 34.37 V, 67.19 V in the case of parallel and series connection when the length of the magnet protruding from the surface of the rotator is 7 mm. Besides that, under the condition of series connection, it is shown that the root-mean-square voltage and power of the circular and rectangular piezoelectric patches are 3.37 V, 0.054 mW, and 10.03 V, 0.80 mW, respectively at 550 r/min when the resistance is 100 kΩ. It can also easily light 47 light-emitting diodes (LEDs) under the excitation of 550 r/min. Therefore, the M−PEH can effectively collect energy under the drive of the inertia wheel and power the microelectronic devices.

Towards single-chip radiofrequency signal processing via acoustoelectric electron\u2013phonon interactions

The addition of active, nonlinear, and nonreciprocal functionalities to passive piezoelectric acoustic wave technologies could enable all-acoustic and therefore ultra-compact radiofrequency signal processors. Toward this goal, we present a heterogeneously integrated acoustoelectric material platform consisting of a 50 nm indium gallium arsenide epitaxial semiconductor film in direct contact with a 41° YX lithium niobate piezoelectric substrate. We then demonstrate three of the main components of an all-acoustic radiofrequency signal processor: passive delay line filters, amplifiers, and circulators. Heterogeneous integration allows for simultaneous, independent optimization of the piezoelectric-acoustic and electronic properties, leading to the highest performing surface acoustic wave amplifiers ever developed in terms of gain per unit length and DC power dissipation, as well as the first-ever demonstrated acoustoelectric circulator with an isolation of 46 dB with a pulsed DC bias. Finally, we describe how the remaining components of an all-acoustic radiofrequency signal processor are an extension of this work.

An experimental study on a piezoelectric vibration energy harvester for self-powered cardiac pacemakers.

BackgroundOver the past half-century, cardiac pacing technology has been reported. In this study, we designed, prepared, and tested the performance of a self-energized cardiac pacemaker driven by piezoelectric vibration energy collection technology, which converts the kinetic energy of the heart into electrical energy. A record in vivo output current of 54 nA was obtained in an adult rat by the implanted piezoelectric transducer.MethodsFirst, the kinetic energy of the heart was collected by an implanted piezoelectric energy collector and supplied to the cardiac pacemaker. Then, the heart was pierced from the outside, and the cardiac tissue was stimulated by the pacing electrode, and self-powered pacing.ResultsThe average voltage and average current of the piezoelectric vibration energy harvester in vitro were 3.5 mV and 60 nA, respectively. After implantation of the device into rats, the average voltage and current were measured immediately and reached 3.2 mV and 54 nA, respectively. The average voltage and average current reached 3.0 mV and 48 nA after 1 week, and 2.1 mV and 31 nA after 12 weeks. The electrical performance of the self-powered pacemaker in this study is based on piezoelectric energy collection technology. The implanted piezoelectric vibration energy collector drives the pacemaker to generate electrical pulses, which directly stimulates the myocardial tissue through the epicardium to achieve the pacing effect.ConclusionsThese results evidence the feasibility of the in-situ epicardial pacing strategy. This research will promote the design and development of self-powered cardiac pacemakers.

Potential energy analysis based on piezoelectric cantilever beam structure

The piezoelectric vibration energy collection technology utilizes the positive piezoelectric effect of the piezoelectric material, and collects the energy by attaching the material to a clamping structure and deforming under the external excitation, thus accumulating the charge and generating the potential difference. In this paper, the cantilever beam is used as a clamping structure because of its large deflection and simple structure. In this paper, the raindrop impulsion is applied to the piezoelectric material, the piezoelectric vibration energy capture device is used to improve the energy collection efficiency, and the electromechanical coupling model is established to simplify the potential energy analysis by using the conservation of energy and Newton’s second law. In this paper, Runge-kutta method is used to simulate the differential equation, which reduces the computational cost of the system and has a certain precision for analysis and solution. Based on Al-‘Ula’s Bernoulli beam theory, the model was simulated by using the differential equation method and the ordinary differential equation group.

Numerical Assessment and Parametric Optimization of a Piezoelectric Wind Energy Harvester for IoT-Based Applications

In the 21st century, researchers have been showing keen interest in the areas of wireless networking and internet of things (IoT) devices. Conventionally, batteries have been used to power these networks; however, due to the limited lifespan of batteries and with the recent advancements in piezoelectric technology, there is a dramatic increase in renewable energy harvesting devices. In this research, an eco-friendly wind energy harvesting device based on the piezoelectric technique is analytically modeled, numerically simulated, and statistically optimized for low power applications. MATLAB toolbox SIMSCAPE is utilized to simulate the proposed wind energy harvester in which a windmill is used to produce rotational motion due to the kinetic energy of wind. The windmill’s rotational shaft is further connected to the rotary to linear converter (RLC) and vibration enhancement mechanism (VEM) for the generation of translational mechanical vibration. Consequently, due to these alternative linear vibrations, the piezoelectric stack produces sufficient electrical output. The output response of the energy harvester is analyzed for the various conditions of piezoelectric thickness, wind speed, rotor angular velocity, and VEM stiffness. It is observed that the electrical power of the proposed harvester is proportional to the cube of wind speed and is inversely proportional to the number of rotor blades. Furthermore, an optimization strategy based on the full factorial design of the experiment is developed and implemented on MINITAB 18.0 for evaluating the statistical performance of the proposed harvester. It is noticed that a design with 3 rotor-blades, having 3 mm piezoelectric thickness, and 40 Nm−1 stiffness generates the optimum electrical response of the harvester.

Transverse Vibration Energy Harvesting of Double Elastic Steel

This study uses the piezoelectric technology to collect vibration energy from the fixed-fixed nonlinear elastic beams attached with the piezo-patch between the two ends. Both single elastic steel sheet (SESS) and double elastic steel sheet (DESS) systems are investigated and correlated. To simulate the power generation of the vibration energy harvester (VEH) of both the SESS and the DESS in different engineering elements, the simple harmonic external force generated by a shaker at the location of the piezo-patch is used as the source. With this, more vibration converted electric energy is derived from the transverse deformation and flapping from the DESS than the SESS beam. The equation of a nonlinear Euler–Bernoulli beam is coupled with the electric energy equation of the piezo-patch to simulate the SESS VEH system. The flapping force from the DESS VEH system can be considered the concentrated external load applied on the SESS beam model. The method of multiple scales (MOMS) is employed to analyze this nonlinear problem. The fixed points plots and the numerical results confirm this theory presented for the two beam systems, which can be used for evaluating similar engineering systems. Experiments are also performed in this study. The Taguchi method is used to analyze the optimum locations of the shaker and piezo-patch, as well as the confidence level of the factors. The method of nonlinear analysis presented in this study demonstrates its accuracy compared with the linear case. The transverse DESS VEH model proposed is proved to be feasible and more effective than the SESS system.

A Review of Piezoelectric Vibration Energy Harvesting with Magnetic Coupling Based on Different Structural Characteristics.

Piezoelectric vibration energy harvesting technologies have attracted a lot of attention in recent decades, and the harvesters have been applied successfully in various fields, such as buildings, biomechanical and human motions. One important challenge is that the narrow frequency bandwidth of linear energy harvesting is inadequate to adapt the ambient vibrations, which are often random and broadband. Therefore, researchers have concentrated on developing efficient energy harvesters to realize broadband energy harvesting and improve energy-harvesting efficiency. Particularly, among these approaches, different types of energy harvesters adopting magnetic force have been designed with nonlinear characteristics for effective energy harvesting. This paper aims to review the main piezoelectric vibration energy harvesting technologies with magnetic coupling, and determine the potential benefits of magnetic force on energy-harvesting techniques. They are classified into five categories according to their different structural characteristics: monostable, bistable, multistable, magnetic plucking, and hybrid piezoelectric–electromagnetic energy harvesters. The operating principles and representative designs of each type are provided. Finally, a summary of practical applications is also shown. This review contributes to the widespread understanding of the role of magnetic force on piezoelectric vibration energy harvesting. It also provides a meaningful perspective on designing piezoelectric harvesters for improving energy-harvesting efficiency.

Piezoelectric Ultrasonic Biological Microdissection Device Based on a Novel Flexure Mechanism for Suppressing Vibration

Biological microdissection has a wide range of applications in the field of molecular pathology. The current laser-assisted dissection technology is expensive. As an economical microdissection method, piezoelectric ultrasonic microdissection has broad application prospects. However, the performance of the current piezoelectric ultrasonic microdissection technology is unsatisfactory. This paper aims to solve the problems of the low dissecting precision and excessive wear of the dissecting needle caused by the harmful lateral vibration of the present piezoelectric ultrasonic microdissection device. A piezoelectric ultrasonic microdissection device based on a novel flexure mechanism is proposed. By analyzing the flexure hinge flexibility, the type of flexure beam and the optimal design parameters are determined. Through harmonic response simulation analysis, the newly designed microdissection device with a vibration-suppressing mechanism achieves the best vibration effect when the driving frequency is 28 kHz. Under this driving frequency, the lateral vibration suppression effect is improved by 68% compared to the traditional effect without vibration suppression. Then, based on 3D printing technology, a prototype of a novel microdissection device is produced, and its performance is tested. Experiments on dissecting needle vibration tests show that the flexure mechanism does indeed suppress the lateral vibration of the needle tip. We conducted various tissue dissection experiments on paraffin tissue sections. First, we determine the optimal dissecting parameters (driving voltage, frequency, feed speed, cutting angle) of the new equipment through various parameter dissecting experiments. Then, we adopt these optimal dissecting parameters to perform three kinds of dissecting experiments on mouse tissue paraffin section (liver, lung, bone), dissecting experiments on tissue sections of different thicknesses (3 μm, 4 μm, 5 μm), sampling and extraction experiments on complete tissue. The new device has a better dissecting performance for paraffin tissue sections below a 5 μm thickness and can complete various dissecting tasks. Finally, we compare the wear of the dissecting needles of the new and old devices after the same dissecting tasks. The results prove that the suppression of harmful lateral vibration not only significantly improves the dissecting effect but also increases the service life and durability of the dissecting needle, which is beneficial for reducing the equipment costs.
