Thin-film “plastic” strain sensors can be mounted closely on textile clothing or human skin comfortably to detect human activities without any harm to the human body. However, it is a grand challenge to prepare highly sensitive and durable plastic strain sensors. Herein, we report a high-performance plastic strain sensor with a sandwich structure of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) doped with poly(vinyl alcohol) (PVA–PEDOT:PSS)/highly conductive PEDOT:PSS/polydimethylsiloxane elastomer. The strain sensor exhibited not only high sensitivities but also good durability at large strains owing to its robust structure integration and strong recoverability in conductance. More importantly, our plastic strain sensors are successfully used to monitor a series of human activities including joint/muscle motions, arterial pulsation and voice vibration, and distinguish some complex and diverse bending motions, demonstrating great potential in practical applications.

使用PEDOT：PSS和弹性体的夹层结构的高度灵敏，耐用且可拉伸的塑料应变传感器†

薄膜“塑料”应变传感器可以舒适地紧密安装在纺织服装或人体皮肤上，以检测人体活动，而不会对人体造成任何伤害。然而，准备高度灵敏且耐用的塑料应变传感器是一个巨大的挑战。在此，我们报告了一种高性能的塑料应变传感器，该传感器具有三明治结构的聚（3,4-乙撑二氧噻吩）：掺杂有聚乙烯醇（PVA–PEDOT：PSS）/高导电性PEDOT：PSS /的聚苯乙烯磺酸盐聚二甲基硅氧烷弹性体。应变传感器由于其坚固的结构集成和很强的电导率恢复能力，不仅在高应变方面表现出高灵敏度，而且还具有良好的耐久性。更重要的是，我们的塑性应变传感器已成功用于监测一系列人类活动，包括关节/肌肉运动，
