Patent ID: 8732938

Claim:
A method of packaging a sensor, the method comprising: affixing a tuning fork to a platform, the tuning fork having tines comprising one or more surfaces, each tine further comprising an electrode and a piezoelectric material, and wherein the electrodes of the tines are positioned to apply electric fields to the piezoelectric materials in the respective tines to move the tines relative to the platform to displace a fluid in contact with the tines; affixing an application specific integrated circuit (ASIC) to the platform; providing electrical communication between the ASIC and the electrode of each tine for providing stimulus to the tuning fork and for receiving a response signal from the tuning fork; and applying a protective layer covering the platform and a portion of the tuning fork while maintaining a portion of a surface of each tine free from the protective layer such that the surface can displace the fluid in contact therewith.
