Abstract: A fabric-based pressure sensor array includes: (1) a first layer including M elongated conductive strips coated thereon; (2) a second layer including N elongated conductive strips coated thereon, the M elongated conductive strips extending crosswise relative to the N elongated conductive strips to define M×N intersections; and (3) a unitary textile sheet extending between the first layer and the second layer so as to overlap the M×N intersections, the textile sheet having a variable resistivity in response to applied pressure so as to define M×N pressure sensors at locations corresponding to the M×N intersections.

Abstract: This invention relates to a system that continuously monitors pressure and force on the foot, analyzes and visualizes the pressure and force exerted on said foot in real-time. The invention measures pressure and force applied to a plurality of sensors placed in various points of an orthotic, shoe, shoe lining, insert, sock or sock type device. If the sensors detect pressure or force, the sensors send a signal to a microcomputer processor located in the shoe that subsequently analyzes and sends the data wireless to either a handheld electronic device, a personal computer, an electronic data capture system or a software program. The handheld electronic device or the personal computer then displays the data to an operator of the device or computer instantaneously; while the data capture system or program forwards the information to a handheld device and/or personal computer.
