- A Discolorable Flexible Synaptic Transistor for Wearable Health Monitoring
A1 Alkuperäisartikkeli tieteellisessä aikakauslehdessä(2024-01-09) Sun, Cui; Liu, Xuerong; Yao, Quanxing; Jiang, Qian; Xia, Xiangling; Shen, Youfeng; Ye, Xiaoyu; Tan, Hongwei; Gao, Runsheng; Zhu, Xiaojian; Li, Run WeiMultifunctional intelligent wearable electronics, providing integrated physiological signal analysis, storage, and display for real-time and on-site health status diagnosis, have great potential to revolutionize health monitoring technologies. Advanced wearable systems combine isolated digital processor, memory, and display modules for function integration; however, they suffer from compatibility and reliability issues. Here, we introduce a flexible multifunctional electrolyte-gated transistor (EGT) that integrates synaptic learning, memory, and autonomous discoloration functionalities for intelligent wearable application. This device exhibits synergistic light absorption coefficient changes during voltage-gated ion doping that modulate the electrical conductance changes for synaptic function implementation. By adaptively changing color, the EGT can differentiate voltage pulse inputs with different frequency, amplitude, and duration parameters, exhibiting excellent reversibility and reliability. We developed a smart wearable monitoring system that incorporates EGT devices and sensors for respiratory and electrocardiogram signal analysis, providing health warnings through real-time and on-site discoloration. This study represents a significant step toward smart wearable technologies for health management, offering health evaluation through intelligent displays.
