Highly efficient human skin systems transmit fast adaptive (FA) and slow adaptive (SA) pulses selectively or consolidatively to the brain for a variety of external stimuli. The integrated analysis of these signals determines how humans perceive external physical stimuli. Here, a self‐powered mechanoreceptor sensor based on an artificial ion‐channel system combined with a piezoelectric film is presented, which can simultaneously implement FA and SA pulses like human skin. This device detects stimuli with high sensitivity and broad frequency band without external power. For the feasibility study, various stimuli are measured or detected. Vital signs such as the heart rate and ballistocardiogram can be measured simultaneously in real time. Also, a variety of stimuli such as the mechanical stress, surface roughness, and contact by a moving object can be distinguished and detected. This opens new scientific fields to realize the somatic cutaneous sensor of the real skin. Moreover, this new sensing scheme inspired by natural sensing structures is able to mimic the five senses of living creatures.

模拟慢速和快速适应性皮肤机械感受器的自供电传感器

高效的人类皮肤系统可以针对各种外部刺激选择性或合并向大脑发送快速自适应（FA）和慢速自适应（SA）脉冲。对这些信号的综合分析确定了人类如何感知外部物理刺激。在此，提出了一种基于人工离子通道系统并结合压电膜的自供电机械感受器传感器，该传感器可以同时执行类似于人类皮肤的FA和SA脉冲。该设备无需外部电源即可检测到具有高灵敏度和宽频带的刺激。为了进行可行性研究，要测量或检测各种刺激。可以同时实时测量诸如心律和心动描记图等生命体征。此外，还有各种刺激，例如机械应力，表面粗糙度，可以区分和检测移动物体的接触。这为实现真实皮肤的体细胞皮肤传感器开辟了新的科学领域。此外，这种受自然感应结构启发的新感应方案能够模仿生物的五种感官。
