We present a self-powered, wireless radio frequency (RF) transmitter based on the combination of triboelectric nanogenerator (TENG) and piezoelectric element, which can send coded signal remotely to a receiver when the sensor is triggered. The piezoelectric element is connected to an energy management module (EMM) which supplies regulated power suitable for powering the RF module; the triboelectric nanogenerators (TENGs) act as sensors, which control the code being transmitted by the RF module. In addition, a switch is embedded in TENG to control the power supply from EMM to the RF module; only at the moment of TENG being pressed, the power stored in EMM (ultimately from the piezoelectric element) is supplied to the RF module, and the intended RF signal is transmitted. The RF signal is then received by the receiver and the transmitted code is deciphered and then visualised by a Labview program on PC. Four TENGs are used as sensing elements of mechanical pressing, and each triggers a different command to be transmitted. It is believed that, with such novel combination of the piezoelectric element for powering and TENG for sensing, this is a novel application of TENG and piezoelectric element to transmit coded RF signal with regulated power supply suitable for many modern electronics. The designed self-powered RF transmission system and the general system structure have potentially widespread applications in wireless communication and sensing, especially in applications where power or electricity is disrupted/unavailable, such as disaster rescue/relief, e.g. entrapment in buildings and natural environments due to lift malfunction, earthquake, landslide, debris flow, and blizzards, etc.

我们提出了一种基于摩擦电纳米发电机（TENG）和压电元件的自供电无线射频（RF）发射器，当触发传感器时，该发射器可以将编码信号远程发送到接收器。压电元件连接到能量管理模块（EMM），该模块提供适合于为RF模块供电的调节功率。摩擦电纳米发电机（TENG）充当传感器，控制由RF模块传输的代码。另外，在TENG中嵌入了一个开关，以控制从EMM到RF模块的电源；仅在按下TENG时，才将存储在EMM中的功率（最终来自压电元件）提供给RF模块，并发送所需的RF信号。然后，RF信号被接收器接收，传输的代码被解密，然后通过PC上的Labview程序可视化。四个TENG用作机械压力的感应元件，每个TENG触发一个不同的命令进行传输。可以相信，通过用于供电的压电元件和用于检测的TENG的这种新颖的组合，这是TENG和压电元件在具有适用于许多现代电子设备的稳压电源下传输编码的RF信号的新颖应用。所设计的自供电RF传输系统和总体系统结构在无线通信和传感中具有潜在的广泛应用，特别是在电力或电力中断/不可用的应用中，例如灾难救援/救济，例如
