Abstract
A self-powered impulse detecting system comprising a signal transmitter; an energy storage component; and an energy harvester comprising a top plate configured to receive a stress impulse by an external object on its top surface; a bottom plate positioned opposite to the top plate and leaving room in between the bottom plate and the top plate; an elastic element positioned in between the top plate and the bottom plate; a bendable substrate attached at a first end to the bottom surface of the top plate, the bendable substrate is configured to bend freely, colliding with the top plate and a stopper; a piezoelectric element positioned on the bendable substrate; a deadweight attached to a second end of the bendable substrate; wherein collisions between the bendable substrate, the top plate and the stopper cause the bendable substrate to bend along with the piezoelectric element to generate power.
