Research On All elastomeric pillars-based triboelectric vibration sensor for self-powered broad range machinery condition monitoring Got Featured On University and News Portals
Industrial vibration monitoring is crucial for anticipating equipment failures and ensuring smooth machinery operations. To address this need, we propose a Siloxene-Ecoflex elastomeric macro-pillared self-powered triboelectric vibration sensor (SP-TVS) that offers exceptional detection capabilities, with an ultra-wide frequency range (0.01–15 kHz) and acceleration range (0.1–7.0 g). The SP-TVS combines a facile fabricated elastomeric macro-pillar of nanocomposite paired with a flexible thin film of styrene-ethylene-butylene-styrene (SEBS) to realize the TVS. The SP-TVS exhibits high-frequency response (up to 15 kHz) due to the random high elastic vibration behavior of the macro-pillars and demonstrates excellent acceleration sensitivity of 2.033 V/g (0.1–0.5 g), 1.455 V/g (0.5–2.0 g), and 1.116 V/g (2.0–7.0 g) at r2 = 0.99 in low, medium, and high acceleration ranges and enables subtle vibration amplitude detections. Finally, the SP-TVS has been successfully deployed on various machineries, employing a sophisticated Artificial Intelligence algorithm to process sensor data, performs self-powered machinery identification, vibration inspection, and fault monitoring, showcasing its significant potential for a wide range of industrial monitoring applications.
