Title: Shear horizontal surface acoustic wave (SH-SAW) resonators and arrays thereof

Abstract

The present application relates to a biosensor that employs an acoustic cavity to store mechanical energy. In particular examples, the biosensor includes an electrode region and one or more reflector regions to form the acoustic cavity, as well as a functionalized active area disposed in proximity to the cavity. Methods of making and using such biosensors are also described herein.
