Abstract

This invention proposes a different approach to powering an RFID tag: rectified voltage where the source of the voltage is a piezoelectric material attached to a part in constant motion. The piezoelectric material is attached in some fashion to the carrier, superstructure, of a disk drive in operation in a computer system.
