Abstract With the rapid development of Internet of things (IoTs), big data collection and analysis based on distributed sensing is particularly important. Here, we report a natural biodegradable wood-based triboelectric nanogenerator (W-TENG), which not only can produce high electric output to power microelectronic devices, but also can be used as a self-powered sensor. A pure natural biodegradable and pollution-free wood is used as the triboelectric material. The output voltage and current of the W-TENG (8 cm × 8 cm) is 220 ± 20 V and 5.8 ± 0.5 μA at a frequency of 2 Hz. The maximum output power density could be as high as 158.2 mW/m2 at a resistance of 50 MΩ. On this basis, The W-TENG can be widely used as self-powered light switch, self-powered doorbell which can realize the intelligent control of the lights and contribute to the energy conservation to a great extent. In addition, it can be designed as a smart floor and installed on the stage wooden floor to track and record the dancers' movements. Moreover, dancers can control the lights themselves through the floor under their feet. This W-TENG based self-powered system breaks new ground for wood-based electronics, which will have potential applications in big data analysis, smart home and smart city environments.
