1. A sensor comprising:
a grid of bars that are in contact from their bottom at bar crossings with a set of protrusions that are in contact from above with a plurality of intersections, each having a sensing element, of a grid of wires disposed on a base, and a top surface layer that is disposed atop the grid of bars, so that force imparted from above onto the top surface layer is transmitted to the grid of bars and thence to the protrusions, and thence to the intersections of the grid of wires which are thereby compressed between the base and protrusions; and that the protrusions above thereby focus the imparted force directly onto the intersections, each sensing element includes FSR; and
a computer in communication with the grid of wires which causes prompting signals to be sent to the grid of wires and reconstructs a continuous position of force on the surface from interpolation based on data signals received from the grid of wires.
