Abstract:
1. A fluid sensor package comprising: a tuning fork resonator on a platform, the tuning fork resonator comprising tines, each tine having one or more surfaces, each tine further comprising an electrode, and a piezoelectric material selected from the group consisting of quartz and lithium niobate, wherein the electrodes are positioned to apply electrical fields to the piezoelectric materials in the respective tines to move said surfaces of the tines relative to the platform to displace a fluid in contact with the tines, an application specific integrated circuit (ASIC) on the platform, the ASIC being in electrical communication with the electrode of each tine for providing stimulus to the tuning fork resonator and for receiving a response signal from the tuning fork resonator, the ASIC being operable to determine one or more characteristics of the fluid from the response signal, and a secondary component on the platform and spaced from the ASIC, the secondary component being selected from the group consisting of a temperature sensor, a field programmable gate array, a calibration unit, a conductive path, a resistor, a capacitor, an amplifier, a filter, and combinations of two or more thereof.
