Abstract
A piezoelectric power generator () comprises plural piezoelectric devices (); an actuator () positioned to impart an excitation to the plural piezoelectric devices () in a predefined sequence; and, an electrical conduction system () connected to the plural piezoelectric devices for conducting an electrical charge created by the excitation. Preferably the plural piezoelectric devices () are arranged in a predetermined relationship relative to the actuator () whereby only one of the plural piezoelectric devices () is actuated at a time. For example, the plural piezoelectric devices () can be arranged in an angular pattern (such as a circular pattern) relative to the actuator (). Preferably, a rotational speed of the actuator () permits an excitation response for a given plural piezoelectric device () to essentially fully decay before the given plural piezoelectric device () is again excited.
