Electroacoustic component with remote identification and/or sensor function for telemetry-sensor systems

摘要

The electroacoustic component uses an interdigital transducer (IDT) applied to a piezoelectric substrate, with at least 2 rows of signal tap-offs, electrically coupled together via a signal bus. The tap-offs are each weighted by an aperture, with the apertures and the spacing of the tap-offs providing an identification code for a remote identification system.
