Method to generate electrical current using a plurality of masses attached to piezoceramic supports

摘要

A method is provided to generate electrical current. The method includes creating a plurality of unitary masses each connected to one of a plurality of piezoceramic mass supports. The mass supports are electrically joined to a sheath. The method also includes removing material from the unitary masses to operably limit a mass vibration deflection. The sheath is attached to a vibrating body. The unitary masses are pre-tuned to match at least one natural frequency mode of the vibrating body. The unitary masses and the piezoceramic mass supports are induced to vibrate to generate the electrical current.
