Surface acoustic wave RF sensing and actuation for lab-on-a-chip platforms

Abstract

This paper presents different surface acoustic wave (SAW) active components including actuators and sensors to realize the whole chain necessary to establish a lab-on-chip system. The SAW actuation is based on the acoustic streaming effect caused by the leakage of SAW into fluids in the microfluidic channel. A novel SAW sensor to determine the optical and mechanical absorption properties of liquid samples in a microfluidic channel is also discussed.
