Pressure sensors are vital components of wearable electronics for human-machine interaction, health monitoring, disease prevention and so on. State-of-the-art pressure sensors often require the use of encapsulating materials such as polydimethylsiloxane (PDMS) to provide the mechanical durability, which significantly deteriorates the detection limit, permeability and wearing comfort of the pressure sensors. This paper reports a new type of encapsulation-free, low-detection-limit, and highly permeable pressure sensors, which are made with resilient graphited knitting hemp fabrics. The hemp sensors possess appealing properties including excellent permeability to air, water vapor, and moisture, low detection limit (0.3 Pa), wide working range (up to 500 kPa) outstanding cycling stability and durability. It provides a new route for achieving wearing comfortable and high-performance pressure sensors.

基于渗透性石墨大麻纤维的,穿着舒适的压力传感器,用于监测人类活动

压力传感器是可穿戴电子设备的重要组成部分,用于人机交互,健康监控,疾病预防等。现有技术的压力传感器通常需要使用诸如聚二甲基硅氧烷(PDMS)之类的封装材料来提供机械耐久性,这大大降低了压力传感器的检测极限,渗透性和佩戴舒适度。本文报道了一种新型的无封装,低检测限,高渗透性的压力传感器,该传感器由弹性石墨编织的麻织物制成。大麻传感器具有吸引人的特性,包括对空气,水蒸气和湿气的优异渗透性,低检测极限(0.3 Pa),宽广的工作范围(高达500 kPa),出色的循环稳定性和耐用性。
