作为精确运动测量的主要组成部分，角度传感器在机器人、机器控制和个性化康复中发挥着至关重要的作用。在过去的几十年里，各种形式的角度传感器已经被开发和优化，但没有一种传感器可以在没有电力的情况下工作。本文报道了一种经过综合优化的高灵敏度摩擦电自供电角度传感器（SPAS），其分辨率最高（2.03纳米弧度）。此外，SPAS具有重量轻、厚度薄的优点，这使得它能够以最小的能耗进行广泛的集成应用：配备SPAS的码垛机械臂可以通过收集的角度数据精确地复制中国传统书法。此外，SPAS可以装配在医疗保险支架中记录关节的屈曲/伸展，这可能有利于个性化矫形康复。SPAS为机器人、传感、个性化医疗和人工智能等新兴领域的应用开辟了新的途径。
As the dominant component for precise motion measurement, angle sensors play a vital role in robotics, machine control, and personalized rehabilitation. Various forms of angle sensors have been developed and optimized over the past decades, but none of them would function without an electric power. Here, a highly sensitive triboelectric self-powered angle sensor (SPAS) exhibiting the highest resolution (2.03 nano-radian) after a comprehensive optimization is reported. In addition, the SPAS holds merits of light weight and thin thickness, which enables its extensive integrated applications with minimized energy consumption: a palletizing robotic arm equipped with the SPAS can precisely reproduce traditional Chinese calligraphy via angular data it collects. In addition, the SPAS can be assembled in a medicare brace to record the flexion/extension of joints, which may benefit personalized orthopedic recuperation. The SPAS paves a new approach for applications in the emerging fields of robotics, sensing, personalized medicare, and artificial intelligence.
