Claim 3:
4. The apparatus of claim 3, further including processing circuitry in communication with the sensor circuitry, wherein the sensor circuitry is to define a magnitude of the normal and shear forces by measuring changes in capacitance derived from changes in a gap distance between the first electrode and the second electrode and provide signals indicative of the magnitude of the normal forces, and comparing changes in capacitance derived from changes in an overlapping area between the first electrode and the second electrode, the third electrode and the second electrode, and the fourth electrode and the second electrode, and the fifth electrode and the second electrode to provide signals indicative of the magnitude of the shear forces to the processing circuitry.
