Abstract
Disclosed is a method of sensing a target analyte in a liquid sample using a bulk acoustic wave resonator device. The liquid sample is placed on the bulk acoustic wave resonator device which is operated to generate bulk acoustic waves. A shift in the fundamental resonant frequency of the bulk acoustic wave resonator device is measured. The bulk acoustic wave resonator device comprises a resonator structure and an acoustic decoupling layer. The resonator structure comprises: a piezoelectric material layer; electrodes arranged to apply a driving signal to the piezoelectric material layer to generate bulk acoustic waves; and a resonator structure surface. The acoustic decoupling layer is formed over the resonator structure surface. The acoustic decoupling layer acoustic impedance is: up to ⅕ times or not less than 5 times the resonator structure acoustic impedance, and up to ⅕ times or not less than 5 times the liquid sample acoustic impedance.
