An intelligent triboelectric sensing system for monitoring and early warning of dry eye syndrome

For recent years, the heavy and prolonged use of electronic devices has resulted in a growing population of dry eye syndrome especially for younger individuals. Due to a lack of public awareness, the rate of seeking medical consultations remains relatively low. The advancement in smart wearable technology has opened up numerous possibilities for early observation of the symptoms such as frequent eye blinking and implementation of subsequent healthcare. In this study, we present a personalized monitoring-feedback system based on a self-powered, wearable, stretchable triboelectric sensor and matching counting module, image display module, and human-computer interaction module. The system is capable of detecting subtle biomechanical signals in the human body with exceptional sensitivity, such as eye blinking. The electronically processed electrical signals can activate a coupled counter and transmit information to mobile devices through the Internet of Things (IoT). This enables automatic processing and interaction with users, providing reminders and correction information regarding eye-related behavior. Through animal and volunteer experiments, we validate the accurate identification of eye-related behavior and the provision of appropriate feedback. This work proposes a promising technological approach for monitoring, early warning and management of dry eye syndrome.

Convolutional Neural Networks‐Motivated High‐Performance Multi‐Functional Electronic Skin for Intelligent Human‐Computer Interaction

A multi-functional electronic skin (e-skin) with high sensitivity and wide response range is crucial for intelligent human-computer interaction (HCI) system. Here, a multi-functional hybrid e-skin (TPES) integrated by a piezo-capacitive pressure sensor (PCPS) and a triboelectric nanogenerator (TENG) is reported. An ion-gel electrospinning doped with MXene is combined with a micro-structured ion-gel to enrich the structural variations of the overall device, enabling TPES to achieve a high sensitivity of 616.42 kPa−1, a broad response range of 0.6 Pa–1 MPa, and a fast response time of 5.6 ms. The vast surface area of the mixed cellulose foam layer effectively enhances the electrical output of the TENG, making TPES’s application scenarios become more flexible. By further integrating the different functionalities of the TPES with one-dimensional convolutional neural networks and HCI module, a gesture recognition and material perception HCI system is realized. Additionally, benefiting from the excellent performance of the PCPS and TENG, a multi-information recognition HCI system is established, capable of simultaneously recognizing the pressure and surface material of the balls and enabling real-time interaction with a virtual character. In summary, the proposed work offers a novel avenue for practical intelligent HCI system in virtual reality field.

Custom-Developed Reflection-Transmission Integrated Vision System for Rapid Detection of Huanglongbing Based on the Features of Blotchy Mottled Texture and Starch Accumulation in Leaves.

Huanglongbing (HLB) is a highly contagious and devastating citrus disease that causes huge economic losses to the citrus industry. Because it cannot be cured, timely detection of the HLB infection status of plants and removal of diseased trees are effective ways to reduce losses. However, complex HLB symptoms, such as single HLB-symptomatic or zinc deficiency + HLB-positive, cannot be identified by a single reflection imaging method at present. In this study, a vision system with an integrated reflection-transmission image acquisition module, human-computer interaction module, and power supply module was developed for rapid HLB detection in the field. In reflection imaging mode, 660 nm polarized light was used as the illumination source to enhance the contrast of the HLB symptoms in the images based on the differences in the absorption of narrow-band light by the components within the leaves. In transmission imaging mode, polarization images were obtained in four directions, and the polarization angle images were calculated using the Stokes vector to detect the optical activity of starch. A step-by-step classification model with four steps was used for the identification of six classes of samples (healthy, HLB-symptomatic, zinc deficiency, zinc deficiency + HLB-positive, magnesium deficiency, and boron deficiency). The results showed that the model had an accuracy of 96.92% for the full category of samples and 98.08% for the identification of multiple types of HLB (HLB-symptomatic and zinc deficiency + HLB-positive). In addition, the classification model had good recognition of zinc deficiency and zinc deficiency + HLB-positive samples, at 92.86%.
