High-performance flexible pressure sensors play an important role in the field of human body detection and human–computer interaction. This study proposes a new low-cost capacitive sensor that can achieve high sensitivity and stability over a wide range of tactile pressures (0–80 kPa). In addition, the nanowires were deposited into a flexible fabric that is embedded in polydimethylsiloxane to form a hydrophilic and hydrophobic layered electrode layer. The multilayer fiber structure of the rib fabric ensures good electrical conductivity. The sensitivity of the sensor that is made from the slanted bionic microstructure is seven times that of the dielectric layer without the microstructure. The measured response recovery time (13.4 ms) is suitable for real-time dynamic monitoring. Because a small temperature has little impact on the sensor, the sensor can be widely used in close-fitting wearable devices. It can also quickly identify the bending movement of the finger joints, as well as the finger pressure. Meanwhile, the sensor shows excellent stability and can withstand more than 7,000 load/unload cycle tests. This sensor has broad application prospects such as human health, motion monitoring, and human-computer interaction control.

基于仿生倾斜花瓣结构嵌入式罗纹织物的柔性电容压力传感器

高性能柔性压力传感器在人体检测和人机交互领域发挥着重要作用。这项研究提出了一种新的低成本电容式传感器，可以在很宽的触觉压力范围 (0-80 kPa) 内实现高灵敏度和稳定性。此外，纳米线被沉积在嵌入聚二甲基硅氧烷的柔性织物中，以形成亲水和疏水的分层电极层。罗纹织物的多层纤维结构保证了良好的导电性。由倾斜仿生微结构制成的传感器的灵敏度是没有微结构的介电层的七倍。测得的响应恢复时间（13.4 ms）适用于实时动态监测。因为很小的温度对传感器的影响很小，该传感器可广泛应用于贴身的可穿戴设备。它还可以快速识别手指关节的弯曲运动，以及手指压力。同时，该传感器表现出优异的稳定性，可承受超过 7,000 次加载/卸载循环测试。该传感器在人体健康、运动监测、人机交互控制等方面具有广阔的应用前景。
