The Resonant Properties of AT-Cut Quartz Resonator and its Application

Abstract:

The applications of quartz for electric devices had been progressed for a long time. In the early period, the primary application of quartz is focused on the crystal resonator and filter^1-4). The other important application of quartz is on the QCM(quartz crystal microbalance). The basic principle of QCM is based on the mass loading effect, which makes the resonator frequency shift and the mass loading is directly proportion to the shift of frequency. V.M.Mecea has shown the theory of mass loading and its applications⁵⁾. For using quartz as microbalance or sensor, an electronic circuit for change the shift of frequency to electronic signal is necessarily. Unfortunate, another important influence of mass loading is the inharmonic mode appearance with large mass load and inconveniently for designs the electric circuit. So a pure fundamental mode resonator is expected for used the quartz as sensor devices.
