Wireless self-powered sensor networks driven by triboelectric nanogenerator for in-situ real time survey of environmental monitoring

Reusing waste materials to create energy harvester will not just reduce the environmental pollution, but also generate renewable electricity by scavenging environmental energy to power wireless electronic devices. In this study, an environmental friendly, multifunctional and fully packaged arc-shaped triboelectric nanogenerator (AS-TENG) by reusing waste milk carton is developed and capable of scavenging both wind and water flow energy efficiently. Moreover, a highly-integrated data acquisition, processing and wireless transmission monitoring system based on AS-TENG is established for real time and long-term water quality (pH value) monitoring and landslide early warning in natural environment.245
