Abstract:

At present, most flexible pressure sensors cannot be disposed and become electronic waste after used due to the using of no-degradable materials, which brings great pressure to the environment. With the development of science and technology, the emergence of biodegradable materials provide a huge opportunity for the reform of flexible pressure sensors. Flexible pressure sensors based on biodegradable materials have become a research hotspot because they play an important role in personal health management, medical monitoring, environmental monitoring and other fields, and they have great potential in reducing electronic waste and alleviating environmental problems. Based on this, the flexible degradable pressure sensors are divided into three types according to the key materials in this paper, which are sensors originated from degradable polymer substrates, sensors come from degradable conductive materials, and sensors produced by double degradation of polymer substrates and conductive materials. Moreover, the latest progress of three kinds of flexible degradable pressure sensors at home and abroad are reviewed. Firstly, the types of key materials and the preparation process of the above three sensors are briefly introduced. Secondly, the advantages, disadvantages and application fields of each type of sensor are summarized. Finally, the problems and development trends of flexible degradable pressure sensors are pointed out to provide reference for the development and application of flexible degradable pressure sensors.

Key words: degradable, flexible pressure sensors, polymer substrates, conductive materials, double degradation

摘要:

目前,大多数柔性压力传感器采用不可降解材料制备,导致在使用完成后无法处理,堆积过多成为电子垃圾,给环境带来很大压力。随着科学技术的发展,可降解材料的出现为柔性压力传感器的变革提供了巨大的机会。基于可降解材料制备的柔性压力传感器由于在个人健康管理、医疗监控、环境监测等领域发挥着重要作用,且在减少电子垃圾,缓解环境问题方面具有巨大潜力,已成为当今的研究热点。基于此,本文从柔性可降解压力传感器的关键制备材料出发,将柔性可降解压力传感器分为基于可降解聚合物基底的柔性压力传感器、基于可降解导电材料的柔性压力传感器以及基于聚合基底和导电材料双降解的柔性压力传感器,并对三类柔性可降解压力传感器的国内外研究进展进行了综述。首先,简单介绍了柔性可降解压力传感器关键制备材料的种类及传感器的制备过程;其次,对每种类型传感器的优缺点及应用领域进行了总结;最后,指出了柔性可降解压力传感器目前存在的问题及今后的发展趋势,以期为柔性可降解压力传感器的开发和应用提供参考。
