The invention relates to a method for interrogating an elastic wave device consisting of probing the response of a resonant, piezoelectric device at a single frequency alternately on either side of a first resonance frequency determined beforehand, in orde...

Remotely interrogating a passive sensor having resonator(s) includes interrogating the resonator over a frequency range determined by the design of the resonator; interrogating the resonator at a first frequency and a second frequency; determining the ampl...
