Abstract: A pressure sensing array for measuring forces applied thereto and particularly for measuring the gait of a person. The pressure sensing array includes a first plurality of current driven electrodes attached to and supported by a thin, flexible backing sheet and a second plurality of current sensing electrodes disposed in an insulating arrangement positioned on the first plurality of current sensing electrodes. A third plurality of bridge electrodes are also provided so as to connect the current driven electrodes and the current sensing electrodes such that upon sensing a pressure on opposite ends of one of said bridge electrodes, an electrical conduction is provided between the current driven electrodes and the current sensing electrodes. A method of manufacturing the apparatus is also disclosed.
