Abstract

See full text

A piezoelectric energy harvesting apparatus includes a housing and a piezoelectric module disposed in the housing. The piezoelectric module includes a piezoelectric wafer unit and a clamp unit clamping the piezoelectric wafer unit. A resilient member is connected between the clamp unit and an inner wall of the housing to transmit an oscillation movement to the clamp unit, which in turn causes oscillation of the piezoelectric wafer unit for generating an electric power. An impact unit extends movably into the housing and is capable of pushing the clamp unit against the resilient member when being subjected to an ambient natural force such that the resilient member generates the oscillation movement.
