Abstract:
A sensing apparatus responsive to shear forces applied thereto comprising:a first plurality of mechanical-electrical sensing components integral with a first rectangular structure and sensing normal forces; a second plurality of mechanical-electrical sensing components integral with a second rectangular structure adjacent and in a cantilever beam configuration to said first rectangular structure and sensing both normal and transverse forces; microelectronic processing means for reading force data obtained by said mechanical-electrical sensing components, temperature, and individual mechanical-electrical sensing component identifying data; and an operator interfacing external antenna transmitting power and an instructional signal to said mechanical-electrical sensing components and thereafter receiving said force, temperature and sensing component identifying data from said microelectronic processing means to determine shear force according to the relationship Shear Force=Vt={square root over ({overscore (V)})}23+4+ . . . +n1âˆ’{overscore (V)}21+2+ . . . +n2.
