13. A method of determining a location of pressure applied to a pressure sensor, comprising:
-
measuring at a first time the electric resistance of a conductive fluid filling each of a plurality of channels embedded in said pressure sensor; measuring at a second time the electric resistance of said conductive fluid filling each of said plurality of channels embedded in said pressure sensor; identifying the channels having the greatest change in electric resistance.
