Sensors are the foundation of modern Internet of Things, artificial intelligent, smart manufacturing etc, but most of them require power to operate without spontaneous unique identifiable function. Herein we propose a novel instantaneous force-driven self-powered self-identified wireless sensor based on triboelectric effect to meet the huge demand of true self-powered wireless sensors. The device consists of a microswitch controlled triboelectric nanogenerator (TENG) in parallel with a capacitor-inductor oscillating circuit, and a wireless transmitter. The system is fully powered by the output of the TENG to generate a resonant frequency containing sensing and device identity information, which is then coupled to the transmitter for realizing a long-range wireless communication. The device, with the multiple functions of energy harvesting, sensing, identity generation and wireless signal transmission, is a standalone device, which responds to each trigger without losing sensing information. It eliminates the requirement of electric components for traditional wireless communication, such as rectification circuit, energy storage units, microprocessor, wireless communication chip, etc. Thus, we developed a true self-powered identifiable wireless sensor with great potential for widespread applications.

传感器是现代物联网，人工智能，智能制造等的基础，但其中大多数都需要电源才能运行，而无需自发的独特可识别功能。在本文中，我们提出了一种基于摩擦电效应的新型瞬时力驱动自供电自识别无线传感器，以满足真正的自供电无线传感器的巨大需求。该设备包括一个与电容器-电感器振荡电路并联的微开关控制的摩擦纳米发电机（TENG），以及一个无线发射器。该系统由TENG的输出完全供电，以生成包含感应和设备标识信息的谐振频率，然后将其耦合到发射机以实现远程无线通信。该设备具有能量收集，传感，身份生成和无线信号传输的多种功能，是独立设备，响应每个触发而不会丢失传感信息。它消除了传统无线通信所需的电气组件，例如整流电路，能量存储单元，微处理器，无线通信芯片，等。因此，我们开发了一种真正的自供电可识别无线传感器，具有广泛的应用潜力。
