With the development of technology, people's demand for pressure sensors with high sensitivity and a wide working range is increasing. An effective way to achieve this goal is simulating human skin. Herein, we propose a facile, low-cost, and reproducible method for preparing a skin-like multi-layer flexible pressure sensor (MFPS) device with high sensitivity (5.51 kPa from 0 to 30 kPa) and wide working pressure range (0-200 kPa) by assembling carbonized fabrics and micro-wrinkle-structured Ag@rGO electrodes layer by layer. In addition, the highly imitated skin structure also provides the device with an extremely short response time (60/90 ms) and stable durability (over 3000 cycles). Importantly, we integrated multiple sensor devices into gloves to monitor finger movements and behaviors. In summary, the skin-like MFPS device has significant potential for real-time monitoring of human activities in the field of flexible wearable electronics and human-machine interaction.
随着科技的发展，人们对高灵敏度、宽工作范围压力传感器的需求日益增加。实现这一目标的有效方法是模拟人体皮肤。在这里，我们提出了一种简便、低成本、可重复的方法，通过逐层组装碳化织物和微皱纹结构的 Ag@rGO 电极，制备具有高灵敏度（0 到 30 kPa 时为 5.51 kPa）和宽工作压力范围（0-200 kPa）的类皮肤多层柔性压力传感器（MFPS）装置。此外，高度模仿皮肤结构的装置还具有极短的响应时间（60/90 ms）和稳定的耐用性（超过 3000 次循环）。重要的是，我们将多个传感器装置集成到手套中，以监测手指运动和行为。总之，这种类皮肤 MFPS 装置在柔性可穿戴电子设备和人机交互领域的人体活动实时监测方面具有巨大的潜力。
