1. A method for measuring a fluid property, the method comprisingproviding a sensor that includes:

  • a substrate having a recess formed therein,a plate disposed within the recess,a plurality of tethers suspendedly attaching the plate to the substrate for enabling reciprocating motion of the plate relative to the substrate, andat least one contact pad on the substrate adapted for electrical signaling communication with a power source and processing electronics,contacting the plate with a test fluid,oscillating the plate relative to the substrate, anddetermining at least one characteristic of the test fluid in response to contact with the plate.
