Abstract

The fabrication and characterization of a microfabricated, fexural plate, acoustic wave delay line is presented for use in the physical translation of fluids and/or biological cells. The device consists of dual interdigitated transducers patterned on a thin film composite membrane of silicon nitride, platinum, and sol gel derived piezoelectric ceramic (PZT). The acoustic properties of the device are presented along with preliminary applications to mechanical transport and liquid delivery systems. Improved acoustic signals and improved mass transport are achieved with PZT over present fexural plate wave devices employing ZnO as the piezoelectric material.
