Abstract

A piezoelectric power generator includes piezoelectric material and an actuator for deflecting the piezoelectric material for the purpose of generating electrical charge. The actuator is arranged for reciprocating movement along a first axis in response to external forces, and is preferably constrained against deviation from said axis via one or more suspension members, by means of which the actuator is suspended. The piezoelectric material may be carried on the underside of the actuator, for deflection into a recess. The actuator may carry circuitry for collecting charge, with the piezoelectric material in electrical contact with said circuitry via a conductor extending through an aperture in the actuator in floating, preferably resiliently biased, contact with the circuitry.
