For the development and application of wearable electronics, a transparent and flexible piezoelectric sensor (TFPS) system is an important component considering the physical motion energy of the human body. This work newly proposes a transparent and biocompatible boron nitride nanosheet (BNNS) material with a TFPS device. The TFPS device is based on BNNS as a piezoelectric active component and PDMS as a flexible element. The device is able to generate electrical energy from mechanical push force and human movement; it has an output voltage of 22 V, output current of 75 nA, output power of 40 µW (power density: 106 μW/cm³), and energy conversion efficiency of 12.6%. In addition, the TFPS device based on BNNS (1.0 wt%) is proposed as a significant step toward devices which are self-powered by the biomechanical movement of the human foot, neck, wrist, and knee, converted into electric energy in various signal forms. It will be deployed as a body-movement sensor.

对于可穿戴电子设备的开发和应用来说，透明且柔性的压电传感器（TFPS）系统是考虑到人体物理运动能量的重要组件。这项工作新提出了一种具有TFPS装置的透明且生物相容的氮化硼纳米片（BNNS）材料。TFPS设备基于BNNS作为压电有源组件，基于PDMS作为柔性元件。该设备能够通过机械推力和人体运动来产生电能。它的输出电压为22 V，输出电流为75 nA，输出功率为40 µW（功率密度：106μW/ cm ^3）），能量转换效率为12.6％。此外，基于BNNS（1.0 wt％）的TFPS设备被认为是朝着通过人的脚，脖子，手腕和膝盖的生物机械运动自供电并以各种信号转换为电能的设备供电的设备迈出的重要一步。形式。它将被部署为人体运动传感器。
