Lower limb force sensing system includes a sensory insole formed of a plurality of thin film material layers arranged in a stack to form a plurality of sensor cells in a pattern that defines a sensor array. A plurality of perforations defined in the thin film material layers extend substantially around a perimeter of each sensor cell to substantially separate each sensor cell from a remainder of the thin film material layers and form a 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. The 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.
