A kit for assisting a disabled person in rehabilitation is disclosed herein. The thick-film power switches are formed by thick-film power transistors manufactured in a process common to external inputoutput circuits IO. The dielectric portion forms a substantial majority of the outer surface of the scalpel such that the conductive portion is only exposed along a thin edge of the scalpel. The method further includes forming a plurality of conductive traces on the routing surface. The digital element is provided upon receiving an indication that the digital element has been selected.
