1. A method for forming a touch screen comprising:
applying a coating including a binder, solvent, pigment and a plurality of pressure sensitive microchips, each pressure sensitive microchip including a pressure sensitive capacitor on a semiconductor substrate, to a substrate surface for a touch screen;
projecting an image for a touch screen interface on the substrate surface for the touch screen;
calibrating the pressure sensitive microchips to features of the image for the touch screen interface; and
activating one of the features of the image by pressure activating the pressure sensitive microchips that are calibrated to that feature.
