ABSTRACT:
A piezoelectric power generator (20, 120) comprises plural piezoelectric devices (22, 122); an actuator (24) positioned to impart an excitation to the plural piezoelectric devices (22, 122) in a predefined sequence; and, an electrical conduction system (30) connected to the plural piezoelectric devices for conducting an electrical charge created by the excitation. Preferably the plural piezoelectric devices (22, 122) are arranged in a predetermined relationship relative to the actuator (24) whereby only one of the plural piezoelectric devices (22, 122) is actuated at a time. For example, the plural piezoelectric devices (22, 122) can be arranged in an angular pattern (such as a circular pattern) relative to the actuator (24). Preferably, a rotational speed of the actuator (24) permits an excitation response for a given plural piezoelectric device (22, 122) to essentially fully decay before the given plural piezoelectric device (22, 122) is again excited.
