Surface acoustic wave device and method for signal amplification of surface acoustic wave element

Abstract

A surface acoustic wave (“SAW”) device including a SAW element, a first material, a luminescence material and a light source, and a method for signal amplification of a SAW element. The first material may be positioned on the SAW element and bound to a target material in a sample. The luminescence material may be bound to the target material. The light source may apply light to the luminescence material. The SAW device and the method for signal amplification of a SAW element using the same allow amplification of a signal of the SAW element by an electromagnetic wave generated when light is applied to the luminescence material.
