Claim 17:
18. A method of forming a sensing apparatus comprising:
printing electrode patterns on flexible substrates to form a capacitor having:
a first flexible substrate having four electrodes arranged in a pattern (“the first electrode”); and
a second flexible substrate having a second electrode that includes sections and is cross-shaped;

providing a dielectric layer having a plurality of dielectric structures arranged in a pattern on the first flexible substrate;
combining the dielectric layer and the second flexible substrate such that the first and second electrodes are separated by the dielectric layer and arranged with an overlapping area with respect to one another; and
detecting diagonal shear forces applied to the sensing apparatus based on changes in capacitance indicated by monitoring the sections of the second electrode,
wherein the sensing apparatus distinguishes between torsion and the diagonal shear forces applied to the sensing apparatus by monitoring changes in the capacitance from the cross-shaped second electrode, wherein a torsion force results in capacitance changes in quadratic and the diagonal shear forces result in capacitance changes in linear.
