摘要

柔性应变传感器具有良好的拉伸性和柔韧性

可有效检测手部运动。采用丙烯酸酯弹性体以及银纳米线（AgNWs）制备柔性应变传感器。采用MSP430F2132芯片作为信号采集和处理单元、NT3H211芯片作为近场通信(NFC)无线传输和能量自采集单元

制备一种基于该传感器的电子系统

用于手指的运动检测。结果显示:该传感器在0%~45%的应变范围下

具有良好的线性度

在10%的应变下拉伸释放循环测试下仍保持良好的电学性能。所制作的电子系统可以有效地检测出手指各个关节的弯曲变化

并且能够将较为复杂的静态手部运动信号通过NFC上传到手机中，实现对虚拟手的运动控制。

Abstract

Flexible strain sensor can effectively detect hand motion due to good stretchability and flexibility.Flexible strain sensor is prepared using acrylate elastomers and silver nanowires(AgNWs).MSP430F2132 chip is used for signal acquisition and processing

and NT3H2111 chip for near field communication(NFC)wireless transmission and energy self-harvesting unit.An electronic system is prepared

based on the sensor for finger motion detection.The results show that the sensor has good linearity in the strain range of 0%~45%

with good electrical performance under 10% strain cyclic testing.The electronic system can effectively detect the bending changes of in each finger joint

and can upload the complex signals of static hand motion to the mobile phone through NFC and achieve motion control of the virtual hand.
