A Highly Sensitive Triboelectric Vibration Sensor for Machinery Condition Monitoring (Adv. Energy Mater. 37/2022)

Vibration Sensors In article number 2201132, Jiyu Wang, Wenbo Ding, and co-workers design a highly sensitive self-powered vibration sensor based on the triboelectric nanogenerator (VS-TENG) for machinery condition monitoring. The VS-TENG can detect vibrations with frequencies ranging from 1 to 2000 Hz and can detect vibrations of low amplitude (≈sub-μm). It has been successfully used to monitor the operating conditions of mechanical gear systems, reaching a recognition accuracy of 99.78%.
