Purpose and goal

Vibration sensors are usually bulky, heavy and need to be driven by electric power, which limits its industrial application. Triboelectric nanogenerator (TENG) has been demonstrated to generate power from different types of vibrations. The project is aiming at developing the basics for early prototypes of new self-powered, small-sized and lightweight TENG vibration sensors.

Expected results and effects

This project will focus on the first step towards a liquid metal based TENG-based self-powered vibration sensor, i.e. a material that can generate an electric potential while introduced in a vibrating environment. The new TENG vibration sensor technology is expected to have more advantages than today’s commercial vibration sensors.

Planned approach and implementation

The project will focus on (1) Preparation and property evaluation of early prototypes of liquid metal based TENG vibration sensors; (2) Investigating effects of structural and materials on TENG based vibration sensor sensitivity and stability.
