The capability of the quartz resonator
to identify changes in the viscosity of liquid samples through an electronic transduction and characterization of its admittance response allows us to carry out the present study to detect in a clear way the changes in concentration of methanol in a common alcoholic drink like Ron.
For automotive applications, there are several advantages of the MEMS oscillator in comparison to a traditional quartz resonator
Hence, [m.sub.q], [[rho].sub.q], [v.sub.q], and [d.sub.q] denote the mass, the mass density, the sound velocity (usually of the shear wave), and the thickness of the quartz resonator

It operates on the basis of a quartz resonator
where cheap commercial quartz tuningforks with attached long probes are used as force sensors to obtain images and to manipulate nanoobjects in liquid media, while quality of the resonator vibrating in air remains high.

Acoustic viscosity is calculated using power loss from the quartz resonator
into the fluid.
It contains an SC-cut quartz resonator
and sustaining electronics that are controlled at a precise temperature to achieve a stable output frequency, and excellent phase noise and aging characteristics, all in a compact size.
[S.sub.1] can be expressed simply in terms of some fixed properties of the quartz resonator
, such as the shear modulus, the electrical capacitance, and the fixed geometrical values of the thickness and electrode area .
The R1800/R3800 oscillators utilize both fundamental mode and third-overtone mode resonators with specific attention given to the electrode geometry and surface finish of the quartz resonator
to achieve superior phase stability.
On the other hand, the relationship between the change in oscillation frequency of a quartz resonator
in contact with liquid and accumulated mass was realized by Kanazawa and Gordon (9) and Hillier and Ward (10), who derived the following equation:
By completely eliminating the quartz resonator
that must be cut and tuned for each crystal oscillator (XO) frequency, the Si500 helps enable extremely short lead times.
