我们报告了一种创新的，大面积的，和自供电的压力映射方法的基础上的摩擦电效应，将机械刺激转化为电输出信号。为了直观地了解摩擦电主动传感器（TEAS）的工作机理，采用解析和数值计算相结合的方法对TEAS的工作机理进行了理论研究。依靠开路电压和短路电流的独特压力响应特性，我们首次在单个器件上实现了静态和动态压力传感。对TEAS的性能进行了一系列的综合研究，获得了高灵敏度（0.31 kPa（-1））、超快响应时间（
We report an innovative, large-area, and self-powered pressure mapping approach based on the triboelectric effect, which converts the mechanical stimuli into electrical output signals. The working mechanism of the triboelectric active sensor (TEAS) was theoretically studied by both analytical method and numerical calculation to gain an intuitive understanding of the relationship between the applied pressure and the responsive signals. Relying on the unique pressure response characteristics of the open-circuit voltage and short-circuit current, we realize both static and dynamic pressure sensing on a single device for the first time. A series of comprehensive investigations were carried out to characterize the performance of the TEAS, and high sensitivity (0.31 kPa(-1)), ultrafast response time (
