Abstract:
1. A method of making a tactile sensing matrix, comprising the steps of: (a) generating a substrate; (b) depositing a first plurality of elongated electrodes, spaced apart, on the substrate along a first orientation; (c) depositing a first plurality of conductive shapes onto each of the first plurality of elongated electrodes, spaced apart so that the conductive shapes form a matrix including columns aligned with the first orientation and rows that are transverse to the first orientation; (d) generating a vertically aligned piezoelectric member at each of the first plurality of conductive shapes to form a plurality of piezoelectric members, the piezoelectric members including a material that forms a Schottky contact with the first plurality of conductive shapes; (e) depositing a second plurality of conductive shapes each on a different piezoelectric member, the second plurality of conductive shapes including a material that forms a Schottky contact with the piezoelectric member; (f) infusing an insulating layer into the piezoelectric members; and (g) depositing a second plurality of elongated electrodes, each along a different row of the matrix so that each of the second plurality of elongated electrodes is in electrical communication with all of the second plurality of conductive shapes of a different row of piezoelectric members,
