Abstract：
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-1 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.
摘要：
随着科技的发展,人们对高灵敏度、宽工作范围的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，我们建议一个简单的，低成本,以及通过逐层组装碳化织物和微皱纹结构Ag@rGO电极制备高灵敏度(5.51kPa-1从0到30kPa)和宽工作压力范围(0-200kPa)的皮肤状多层柔性压力传感器(MFPS)装置的可再现方法。此外,高度模仿的皮肤结构也提供了一个极短的响应时间（60/90毫秒）和稳定的耐久性（超过3000次循环）的装置。重要的是,我们将多个传感器设备集成到手套中，以监测手指的运动和行为。总之,在柔性可穿戴电子和人机交互领域，类似皮肤的MFPS设备在实时监测人类活动方面具有巨大的潜力。
