A device for responding to touch discrimination comprises an array of optical fibers distributed over a supporting substrate and a UV holographic processor is connected to the fibers rendering the fibers capable of responding to touch discrimination and location identification. The substrate is an artificial limb having the array of optical fibers thereon that have a density substantially similar to that of the human body. Wavelength comparators are associated with the optical fibers, the wave length comparators providing numerous sensing locations in a single fiber strand as part of a complete fiber optic network for mechanical actuation and sensory feed back.
