All-elastomer 3-axis contact resistive tactile sensor arrays and micromilled manufacturing methods thereof

A system for measuring a sensed output of at least one tactile sensor comprising:

• at least one tactile sensor;
• and
• a microprocessor in electrical communication with the at least one tactile sensor,
• wherein the at least one tactile sensor includes:
• an insulating layer defining a surface;
• and
• a conductive layer formed on the surface of the insulating layer,
• the conductive layer defining at least one group of flexible projections extending orthogonally from the surface of the insulating layer,
• the at least one group of flexible projections including
• a major projection extending a distance orthogonally from the surface of the insulating layer;
• and
• at least one minor projection that is adjacent to and separate from the major projection,
• the at least one minor projection extending orthogonally a distance from the surface of the insulating layer,
• wherein the major projection extends a distance orthogonally from the surface of the insulating layer that is greater than the distance by which the at least one minor projection extends orthogonally from the surface of the insulating layer.
