Patent attributes
A sensor having a set of plates that are in contact from their bottom at the corners 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 set of plates, so that force imparted from above onto the top surface layer is transmitted to the plates 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. A sensor includes a computer in communication with the grid which causes prompting signals to be sent to the grid and reconstructs a continuous position of force on the surface from interpolation based on data signals received from the grid. A method for sensing.
