Wearable pressure sensors, which can perceive and respond to environmental stimuli, are essential components of smart textiles. Here, large-area all-textile-based pressure-sensor arrays are successfully realized on common fabric substrates. The textile sensor unit achieves high sensitivity (14.4 kPa ), low detection limit (2 Pa), fast response (≈24 ms), low power consumption (<6 µW), and mechanical stability under harsh deformations. Thanks to these merits, the textile sensor is demonstrated to be able to recognize finger movement, hand gestures, acoustic vibrations, and real-time pulse wave. Furthermore, large-area sensor arrays are successfully fabricated on one textile substrate to spatially map tactile stimuli and can be directly incorporated into a fabric garment for stylish designs without sacrifice of comfort, suggesting great potential in smart textiles or wearable electronics.
可感知和响应环境刺激的可穿戴压力传感器是智能纺织品的重要组成部分。在这里,大面积基于全纺织的压力传感器阵列成功地在普通织物衬底上实现。该纺织传感器单元具有高灵敏度(14.4 kPa)、低检测限(2 Pa)、快速响应(≈24 ms)、低功耗(<6 µW)和在恶劣变形下的机械稳定性。由于这些优点,该纺织传感器能够识别手指运动、手势、声振动和实时脉搏波。此外,大面积传感器阵列成功地在一个纺织衬底上制造,以空间映射触觉刺激,并可以直接集成到织物服装中,而不会牺牲舒适性,为智能纺织品或可穿戴电子产品提供了巨大的潜力。
