摘要： A sensing system includes an acoustic wave device comprising a body of piezoelectric material, and a first electrode assembly mounted on the piezoelectric body whereby an appropriate input applied to the electrode assembly produces an acoustic wave in the piezoelectric body and a first frequency response. The acoustic wave device also has a second electrode assembly to produce a second frequency response, the second electrode assembly being in contact with an area sensitive to a supplied stimulus to cause a characteristic of the sensitive area to change when a supplied stimulus is sensed to thereby change the second frequency response. The acoustic wave device has an output connected to the input of an amplifier, the amplifier having an output connected to the input of a coupling device. The coupling device is connected to the input of the acoustic wave device and has an output connected to a detector. The acoustic wave device, the amplifier and the coupling device are configured to be in an “off” condition when no supplied stimulus is sensed by the sensitive area of the acoustic wave device and to be in an “on” condition when a supplied stimulus is sensed by the sensitive area. The coupling device is configured to send a change signal to the detector when a change from the “off” condition to the “on” condition occurs.

摘要： The various embodiments of the present disclosure relate generally bulk-acoustic-wave resonators. An exemplary embodiment of the present invention provides a bulk-acoustic-wave resonator comprising an acoustic reflector, a substantially c-axis oriented hexagonal crystal structure, and a plurality of electrodes. The crystal structure is solidly-mounted to the acoustic reflector. The bulk-wave resonator resonates in at least two non-harmonically-related operational modes.

摘要： An acoustic wave sensor assembly includes piezoelectric material, a first acoustic wave resonator element structure mounted on the piezoelectric material for interacting with an electrical signal, the acoustic wave resonator element structure being operable to interact with an acoustic wave propagating within the piezoelectric material to produce a first frequency response. Further acoustic wave resonator element structures are mounted on the piezoelectric material for interacting with electrical signals, the further acoustic wave resonator element structures being operable to interact with further acoustic waves propagating within the piezoelectric material to produce subsequent frequency responses. The first acoustic wave resonator element structure and further acoustic wave resonator element structures are combined to form a ladder or lattice filter network to produce an overall frequency response. Sensitive areas are mounted on the piezoelectric material and associated with the acoustic wave resonator element structures which, if predetermined effects to be sensed or detected are present, are modified thereby to control the nature of the frequency responses with resultant specific perturbations of the combined frequency response and thereby provide information with respect to the predetermined effects to be sensed or detected.
