摘要
柔性压力传感器作为一种新型的电子器件,它在人机交互、医疗健康、机器人触觉等应用领域具有比刚性传感器更大的优势,但也对材料提出了更严格的要求.例如,它要求构成器件的材料很薄、较软,在某些情况下可贴合于人体皮肤表面或者植入体内,这进一步要求材料具有良好的生物相容性,并能与生物组织实现良好的力学匹配.在器件性能方面,柔性压力传感器的设计主要关注于灵敏度、响应时间、检测限、稳定性等性能的提高.最近,研究者们又将目光拓展到了器件的压力响应范围、压力分辨率、空间分辨率及拉伸性能等,使得传感器具有更广阔的应用前景.本篇综述介绍了近年来柔性压力传感器研究的进展,主要包括柔性压力传感器的传感原理、传感性能及应用前景,并最后对该类器件的发展进行了展望.
As an emerging type of electronic devices,flexible pressure sensors have more advantages than rigid sensors in human-computer interaction,healthcare,and tactile sensing in robots.These advantages,however,require the materials to be thin and soft.For applications in human bodies,the sensor needs to be biocompatible and mechanically match the biotissue such that they can be conformable to the skin textures,or be implanted in the body.Sensitivity,response time,limitation of detection,and stability are basic properties to evaluate a pressure sensor.Recently,some other parameters of flexible pressure sensors including pressure response range,pressure resolution,space resolution,and stretchability have also been studied,enabling such devices to have a wider application prospect.This review introduces about the state of the arts of flexible pressure sensors in recent years,and is intended to discuss the sensing mechanisms,properties,and potential applications of flexible tactile sensors.At last,we talk about the future of flexible tactile sensors.
