Abstract
Piezoelectric resonant blade elements (PRB) are useful in applications such as light choppers, laser beam scanners, fans and others. Three methods are proposed for extracting the parameters of the PRB equivalent circuit model: two are direct methods and one is based on an iteration procedure that looks for the least square error. Drive needs for a PRB are discussed and possible drive alternatives are explored. The results of theoretical derivation for parameter extraction and drive requirements were verified against simulation and experiments.
