(a) A circuit diagram of the self-powered wireless environmental node (pressure-temperature-humidity) for IoT applications enabled by H-TENG. (b) The power management circuit, battery, router, environmental sensor node, H-TENG and a wireless module. (c) The temperature, pressure, and humidity are transmitted from the wireless sensor node system to a mobile and a computer screen. The inset figure shows the enlarged values of sensor outputs on a web browser in a laptop as its IoT application.
