Purpose and goal
In this project, a new kind of self-powered TENG vibration sensor was developed for smart technological improvements. We have demonstrated that gallium-based liquid metal can be used in the TENG vibration sensor. The structure and material were optimized for the design of the TENG vibration sensor. This project has generated some interesting results to be the base of a continuation study to be able to take the innovation closer to market.
Expected results and effects
We have prepared a new kind of self-powered, small-sized, lightweight TENG vibration sensor for condition monitoring of machine components. We have demonstrated that Gallium-based liquid metal could be used in the TENG vibration sensor. Semi-sphere and ellipsoid shapes could be used in the TENG vibration sensor design.
Planned approach and implementation
The TENG vibration sensor was prepared via the acrylic plastic sheet, thin copper film on the acrylic shell, polymer film and gallium-based liquid metal droplet. The lab scale evaluation of TENG vibration sensors was performed. In addition, the effects of different structural designs (cone, semi-sphere, ellipsoid, cylinder) and materials on the vibration sensor performance of TENG sensor were investigated.
