Abstract

Abstract: With the development of the Internet of Things (IoT), the power supply to trillions of IoT nodes has become a serious challenge. It is of significant importance to propose a rational power management scheme for constructing fully self‐powered systems using triboelectric nanogenerators (TENG). In this study, as inspired by an embroidery hoop, a new type of TENG without the Helmholtz resonant cavity is developed for collecting sound energy, which can generate the V oc and I sc up to 500 V and 124 µA, respectively at a resonance frequency of 170 Hz and sound pressure of 110 dB. Furthermore, the sound‐driven TENG integrated with a specially designed power management circuit derived from the universal power management strategy (PMS) can successfully drive a commercial narrow band‐IoT wireless node, which realizes periodic temperature and humidity data acquisition and transmission. With the same strategy, an electric switch and a temperature and humidity acquisition system based on Bluetooth technology can also be powered by a contact‐separated TENG and a wind‐driven TENG, demonstrating excellent versatility, adaptability, and universality of the PMS. This study provides a novel solution for the application of TENG in the field of low‐frequency IoT in local and wide areas. Abstract : This study not only presents a sounddriven triboelectric nanogenerator (TENG) integrated with an embroidery hoop but also proposes a universal power management strategy (PMS). The PMS can provide a valuable reference for the further design of specific energy management integrated circuit for the TENG, which is important to promote the commercial application of micro‐nanoenergy.
