Title:
SURFACE ACOUSTIC WAVE ELEMENT IDENTIFYING DEVICE AND ELASTIC WAVE ELEMENT IDENTIFYING DEVICE
Document Type and Number:
Japanese Patent JP2006121234
Kind Code:
A
Abstract:

To provide an inexpensive identifying device of a surface acoustic wave or elastic wave element available as a micro object for analyzing a substance in which a variety of elements can be identified easily.

The surface acoustic wave element identifying device for identifying surface acoustic wave elements 10A, 10B and 10C each having a surface acoustic wave propagation path provided on the spherical outer surface of a substrate 12, and a means 14A, 14B, 14C for generating a surface acoustic wave on the propagation path and detecting the propagating surface acoustic wave comprises propagation characteristics alteration means 14A, 14B and 14C provided on the outer surface of the substrate and altering the propagation characteristics of a surface acoustic wave propagating along the propagation path, and means 23 and 23a for identifying a surface acoustic wave element from the propagation characteristics of desired values of a surface acoustic wave detected by the surface acoustic wave generating/detecting means.
