What is it about?
We demonstrate that an electrostatic levitation microelectromechanical systems (MEMS) switch can be operated by applying mechanical pressure to a triboelectric generator.

Why is it important?
By combining her two research areas of MEMS and energy harvesting, we can design air bag switches to be immediate, so it responds faster. The combination has a unique property that does not need any processing between the time the impact receives and the moment switch opens. It also will be more reliable because then there is no danger of failure for software or hardware. It’s totally self-powered.
Perspectives
The proposed system can also be used in helmet research to find out the spots that need reinforcement.
