Characterization of Suspended Piezoelectrically Transduced Resonators

Maxime Jean Thomas Ehret

This report presents the characterization of singly-clamped and doubly-clamped resonator devices. Resistance tests were performed to ensure adequate top-to-bottom insulation, allowing the characterization work to proceed. The piezoelectric characteristics ...
