Abstract : An extension is presented of an effort to develop a piezoelectric energy converter with major emphasis on acoustic to electric transduction. Both thickness and flexural mode devices were chosen for evaluation. Three ceramic transducer materials were manufactured in a variety of shapes and sizes that would allow investigation of these operational modes. Theoretical response of a thickness mode receiver for plane waves is discussed and power output ratios are found for three ceramic materials. Initial low field test data is presented for a thickness mode device and for three flexural mode devices. The flexural elements tested are edge supported bilaminar discs, each of a different ceramic material. The transducers are being designed with the capability of operating in a 173 db sound field.
