Battery-Free Wireless CO2 Monitoring System Developed
2025-06-16

A research team from the Korea Advanced Institute of Science and Technology (KAIST) has developed a battery-free wireless carbon dioxide (CO2) monitoring system. This system utilizes ambient vibrations, converting them into electricity via an inertia-driven triboelectric nanogenerator (TENG) to periodically measure and wirelessly transmit CO2 concentrations. This innovation overcomes limitations of existing CO2 monitoring systems that rely on batteries or wired power, offering a more convenient and efficient solution for environmental monitoring and paving the way for self-powered environmental monitoring platforms incorporating various sensors.
