Abstract

With the increasing interest in monitoring health and rapid growth in technology of electronic devices, personal wearable electronics have attracted extensive attention in the recent years. By integrating wearable electronic devices into clothing, accessories, electronic skin products, real-time monitoring and diagnosis of human movement and physiological conditions can be realized. In particular, electrospun micro/nanofibers (MNFs) have the benefits of good breathability, low cost and light weight, owing to their high specific surface area and flexible characteristics making them convenient for wearable devices. In this review, we summarized the existing technologies for synthesizing electrospun MNFs, and classified the materials for preparing wearable physical sensors. Besides the performance and functions of MNFs-based physical sensors; the structure, arrangement and post-treatment of electrospun MNFs have also been described in detail. The operating mechanisms of MNFs-based physical sensors mainly including piezoresistive, piezoelectric, capacitive, triboelectric, thermal-resistive and pyroelectric sensors were briefly discussed, and the typical wearable physical sensory applications based on electrospun MNFs were demonstrated as well.

摘要

随着人们对健康监测的兴趣日益浓厚以及电子设备技术的快速发展，个人可穿戴电子产品近年来引起了广泛的关注。通过将可穿戴电子设备集成到服装、饰品、电子皮肤产品中，可以实现对人体运动和生理状况的实时监测和诊断。特别是，静电纺微/纳米纤维（MNF）具有透气性好、成本低和重量轻的优点，由于其高比表面积和柔性特性使其方便用于可穿戴设备。在这篇综述中，我们总结了现有的静电纺丝MNF合成技术，并对制备可穿戴物理传感器的材料进行了分类。除了基于 MNF 的物理传感器的性能和功能之外；静电纺丝MNF的结构、排列和后处理也得到了详细描述。简要讨论了基于MNF的物理传感器的工作机制，主要包括压阻式、压电式、电容式、摩擦电式、热阻式和热释电式传感器，并演示了基于静电纺丝MNF的典型可穿戴物理传感应用。
