Microfluidic Patterning

Interactions between substrate waves and microchannel walls generate spatially localized periodic acoustic forces for microscale patterning activities. We develop analytical models that can be readily applied to predict this periodicity.

High Degree

Considerable and continuing interest has been shown in the thin film transducer fabrication for surface acoustic waves (SAW) in the past few years. Due to the high degree of miniaturization, compatibility with silicon integrated circuit technology, simplicity and ease of design, this new technology has played an important role in the design of new devices for communications and signal processing. Among the commonly used piezoelectric thin films, ZnO generally yields superior electromechanical properties and is expected to play a leading role in the development of SAW devices.
