ABSTRACT
With the advent of the new era of the internet of things (IoT), data acquisition and analysis based on distributed sensors is becoming more and more important. Here, we designed a novel double-arch triboelectric nanogenerators (DA-TENG) based on the polytetrafluoroethylene (PTFE) film and the Nylon film. A self-powered grip exerciser test system based on the DA-TENG has been developed, and it can reflect the grip strength and exercise frequency. The WT-TENG can stay stable output performance several consecutive operations and has wonderful electrical output. The maximum Voc and Isc of DA-TENG can achieve 394.98 V and 37.48 µA, respectively. And the maximum output power can arrive at 1.0368 mW. This work will promote the development of intelligent sports.
