Abstract

Relaxor ferroelectric materials have been studied extensively in both theory and experiments for many years. Their applications to medical ultrasonic transducers have also been investigated. In this paper, we report an experimental study of a composite relaxor ferroelectric transducer and its nonlinear phenomenon at certain bias voltages. Novel applications of the relaxor transducer to diffraction-limited beam production, acoustic power measurement, low speckle medical imaging, and high resolution pulse-echo imaging are discussed.
