Abstract

The efficiency of energy conversion by piezoelectric devices depends upon the quality factor Q, and electromechanical coupling coefficient k². Efficiency, Q, and k² were measured for a piezoelectric cantilever and piezoelectric stack, and compared to a model of the efficiency in terms of Q and k². The model and experiment agree very well.
