摘要
近年来,伴随可穿戴电子设备与日俱增的需求,成本低廉、绿色环保、可批量生产的纸基传感器得以快速发展.然而,目前的纸基传感器仍有两大挑战亟待解决:(1)广泛使用金属电极,极大地削弱了纸的本征优势.(2)传感机理受限于单一触觉感知功能,难以满足多重刺激感知的需求.本文报道了一种基于聚吡咯(PPy)的电容-电阻双模式全纸基传感器.该器件能够感知接近和压力刺激,从而能够应用于人体运动的监测、接近物体的感知.此外,我们还借助该传感器实现了接触式和非接触式摩斯电码输入,并能实现两种模式下的准确区分.该接近-压力全纸基传感器结构简单,容易制造,在可穿戴设备和绿色电子等领域有着巨大潜力.
In recent years,with growing demands for wearable electronics,the paper-based sensors have been developed rapidly due to its low-cost,environment-friendly and easy-making features.However,there are two obvious challenges that are awaiting to be solved:(1)The use of metal electrodes in most paper-based sensors largely weakens the inherent advantages of paper;(2)The sensing mechanism is limited to a single tactile function,which makes it difficult to perceive multiple stimuli.Here,we reported a capacitive-resistive all-paper-based sensor based on polypyrrole(PPy).The device can perceive approaching and pressure stimulation,so it can be applied to detect human motion and sense approaching objects.Moreover,we use the sensor to realize contact and non-contact Morse code input,and achieve an accurate distinction between the two modes.Our all-paper-based capacitive-resistive sensor has a simple structure for easy fabrication and has great capacity in the fields of wearable devices and green electronics.
