Abstract:
A flexible tactile imager includes an array of sensing cells that measure shear force and normal force. The sensing cells include a first sub-cell and a second sub-cell. Each sub-cell includes multi-fingered capacitors configured to measure shear force in a first or second direction and to measure the normal force. The multi-fingered capacitors include a flexible printed circuit board, a comb-like fingered sense electrode and drive electrode patterned on a layer of the flexible printed circuit board, a deformable dielectric material positioned above the comb-like fingered sense and drive electrodes, the comb-like fingered floating electrode patterned above the deformable dielectric material, 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.
