Abstract
A surface acoustic wave (SAW) device comprises an interdigitated transducer structure and at least one acoustic wave reflective structure provided on or in an acoustic wave propagating substrate. The interdigitated transducer structure comprises a first material and the at least one acoustic wave reflective structure comprises a second material different from the first material and/or the acoustic wave reflective structure and the interdigitated transducer structure have different geometrical parameters. A sensor comprises a SAW device as described herein, and a method is used for manufacturing a SAW device comprising at least one acoustic wave reflective structure.
