Lower limb force sensing system

A lower limb force sensing system, comprising:

• a sensory insole formed of a plurality of thin film material layers arranged in a stack to form a plurality of sensor cells arranged in a pattern to define a sensor array, each of said sensor cells comprised of a pressure sensitive pad disposed between opposing top and bottom electrically conductive layers;
• a plurality of perforations defined in the thin film material layers which extend substantially around a perimeter of each sensor cell to substantially separate each sensor cell from a remainder of the thin film material layers forming the sensory insole, the plurality of perforations defining for each sensor cell at least one hinge member which extends from each sensor cell to an interstitial portion of the thin film layers extending between adjacent ones of the sensor cells;
• wherein said at least one hinge member comprises electrical connections respectively between portions of the top and bottom electrically conductive layers disposed in said interstitial portion of the thin film layers and the top and bottom electrically conductive layers disposed within the perimeter of each sensor cell, and said at least one hinge member defines an axis of rotation about which the sensor cell can pivot independently relative to adjacent interstitial portions of the thin film material layers.
