Claim:
1. A flexible tactile imager for measuring normal force and shear force in a first and second direction comprising: a flexible printed circuit board; a comb-like fingered sense electrode patterned on a layer of the flexible printed circuit board; a comb-like fingered drive electrode patterned on the same layer of the flexible circuit board as the sense electrode; a comb-like fingered floating electrode patterned above a deformable dielectric material; a deformable dielectric material sandwiched between the comb-like fingered sense and drive electrodes, wherein the deformable dielectric material allows for lateral movement of the comb-like fingered floating electrode with respect to the comb-like fingered drive electrode and the comb-like fingered sense electrode; a first capacitance formed between the comb-like fingered sense electrode and the comb-like fingered floating electrode; and a second capacitance formed between the comb-like fingered drive electrode and the comb-like fingered floating electrode.
