Wearable sensors have been widely studied because of their small size, light weight, and potential for the noninvasive tracking and monitoring of human physiological information. Wearable flexible sensors generally consist of two parts: a flexible substrate in contact with the skin and a signal processing module. At present, wearable electronics cover many fields, such as machinery, physics, chemistry, materials science, and biomedicine. The design concept and selection of materials are very important to the function of a sensor. In this review, we summarize the latest developments in flexible materials for wearable sensors, including developments in flexible materials, electrode materials, and new flexible biodegradable materials, and describe the important role of innovation in material and sensor design in the development of wearable flexible sensors. Strategies and challenges related to the improvement of the performances of wearable flexible sensors, as well as the development prospects of wearable devices based on flexible materials, are also discussed.
可穿戴传感器因其体积小、重量轻且能够非侵入式跟踪和监测人体生理信息而受到广泛研究。可穿戴柔性传感器通常由两部分组成：与皮肤接触的柔性基底和信号处理模块。目前，可穿戴电子产品涵盖机械、物理、化学、材料科学和生物医学等多个领域。传感器的功能设计理念和材料选择非常重要。在这篇综述中，我们总结了可穿戴传感器用柔性材料的最新进展，包括柔性材料、电极材料和新型柔性可生物降解材料的发展，并描述了材料和传感器设计创新在可穿戴柔性传感器发展中的重要作用。还讨论了与提高可穿戴柔性传感器性能相关的策略和挑战，以及基于柔性材料的可穿戴设备的发展前景。
