We studied the coupled dynamic behavior of a quartz-crystal-resonator (QCR)/microbeams
system in the thickness-shear motions. Through taking into account the couple stress in
the dynamic equations of the quartz plate, both continuous conditions of shear force and bending
moment at the resonator/micro-beams interface are realized. Frequency shift of the compound
QCR system induced by micro-beams is studied in detail. The obtained results are useful in device
design and frequency-stability analysis of quartz crystal resonators.
