KAIST: KAIST Succeeds in Real-Time Carbon Dioxide Monitoring Without Batteries or External Power. “The core of this new system is an ‘Inertia-driven Triboelectric Nanogenerator (TENG)’ that converts vibrations (with amplitudes ranging from 20-4000 ㎛ and frequencies from 0-300 Hz) generated by industrial equipment or pipelines into electricity. This enables periodic CO2 concentration […]
