Abstract

Various types of acoustic wave devices based on surface acoustic, acousto-optic and photoacoustic effects are increasingly used for many biomedical applications. This paper reviews the basic physical phenomena of the acoustic wave propagation and photoacoustic and acousto-optic interactions, which determine their sensing capabilities, and discusses recent applications of these devices in biology and medicine.
