摘要： 具有高灵敏度和快速响应时间的电子皮肤在人体信号监测和机器人领域有广阔的应用前景.模仿人体皮肤的结构，提出了一种自锁型的电子皮肤，上层为规则的金字塔阵列，下层为不规则的起伏.该器件最高灵敏度达到190.4kPa-1，最低探测压力为32Pa，响应时间为8ms，回复时间为8ms，在 3000 次循环载荷下表现出很好的稳定性.该器件制备工艺简单，模具可循环使用，满足大规模生产的条件.将该器件应用于分辨不同的机械力和监测人体的生理信号，表现出良好的性能，发展潜力巨大.

Abstract: Electronic skin with high sensitivity and fast response time has great application prospects in human body signal monitoring and robotics. By imitating the structure of human skin, this paper proposes a self-locking type of electronic skin, whose upper layer is a regular pyramid array, and the lower layer is irregular undulations. The device has a maximum sensitivity of 190.4kPa-1, a minimum detection pressure of 32Pa, a response time of 8ms, a recovery time of 8 ms, and an excellent stability under 3000 cycles of loading. The device has a simple preparation process and the mold can be recycled to meet the conditions of mass production. The device is applied to distinguishing different mechanical forces and monitoring physiological signals of the human body. It shows good performance and has great development potential.

Key words: electronic skin; sandwich structure; pyramid structure; high sensitivity
