Abstract

A series of small, low-cost, underwater and biomedical transducers were developed based on extrusion technology. Miniature versions of the high-power, low-frequency transducers were optimized to produce broadband transmit and receive response, engineered vibration modes, and acoustic beam patterns. The acoustic vibration modes, resonance frequencies, and radiation patterns of the transducers were controlled through the symmetry of the transducer material and its external shape, poling pattern, the driving and receiving electrode geometries, and driving conditions. Finite element analysis methods were used extensively to design the transducers, analyze their response, and refine the geometries based on experimental results.
