Passive and wireless acoustic wave accelerometer

摘要

An acoustic wave acceleration sensor comprises an acoustic wave device including a plate that functions as a propagation medium and at least one interdigital transducer configured upon the plate. One or more antennas can be integrated with the acoustic wave device, wherein the antenna(s) communicates with interdigital transducers. Such antennas can receive wireless interrogation signals and transmit signals indicative of acceleration data.
