Acoustic Transduction Materials and Devices

Abstract

Develop improved, more reliable air and underwater acoustic transducers, encompassing a wide frequency spectrum from 10 Hz to 100 MHz with systematic and conjunct studies on materials, devices, modeling, and electronics. Develop high performance piezoelectric materials (high strain, agile, low loss piezoelectrics) and related ecological materials with improved reliability for better transduction devices. The applications are to Cymbal and Tonpilz transducer arrays for 3 - 50 kHz sonars, thin/thick film transducers for 10 - 100 MHz medical acoustic devices, underwater intensity sensors for low frequency surveillance, and flexural amplification mechanisms of the solid state strain for air acoustic transduction. Modeling and computer simulations of domain motions and structural vibrations and supporting electronics will be developed.
