The “flipping over” process in the fabrication of finger-tip electronics: (a) a finger-tube at the natural, stress-free state on a plastic model of the hand; (b) a “flipping-over” process releases the finger-tube from the model to expose its inner surface; (c) the flipped finger-tube with the electrotactile stimulators on the outer surface; (d) the finger-tube slipped onto the finger model; (e) the “flipping-over” process for the second time moves the electrotactile stimulators from the outer to the inner surface.
