摩擦纳米发电机的自驱动手指动作传感器

Self-driven Finger Motion Sensor Based on Triboelectric Nanogenerator

近年来,摩擦纳米发电机理论的形成和可穿戴电子设备的飞速发展让越来越多的智能环保电子器件走进了人们的生活。本文利用聚四氟乙烯、硅橡胶、铜、聚对苯二甲酸乙二醇酯等易获取材料设计了一种基于摩擦纳米发电机原理的自驱动手指动作无线传感器。通过感受手指弯曲的动作,可使摩擦纳米发电机最高产生1.1V的电压。产生的电压经过检测和处理可以实现对家用电器的无线开关控制。这种新型的传感器展现了在物联网和智能可穿戴设备的巨大应用前景。

Recently,with the formation of the triboelectric nanogenerator theory and the rapid development of wearable electronic devices,an increasing number of intelligent eco-friendly electronic devices have entered people＇s life.In the paper,a self-driven finger motion wireless sensor based on the principle of triboelectric nanogenerator by using some easily accessible materials like PTFE,silicone rubber,copper,polyethylene terephthalate,etc.By sensing the bending movement of the fingers,the triboelectric nanogenerator can produce a maximum voltage of 1.1 V.After being detected and processed,the generated voltage can control the wireless switch of household appliances.The new sensor shows a huge application prospect of Internet of things and smart wearable devices.
