Abstract

A device is provided for simultaneous determination of forces, comprising an arrangement of parallel springs with integrated piezoresistive resistances in the form of a full Wheatstone bridge. The parallel springs, have, for example, silicon or fused quartz, are arranged in lines, wherein the parallel springs at their ends are permanently connected by silicon or fused quartz spacers. At the free ends of the parallel springs, measurement-technology elements are arranged. The opposite ends of the parallel springs are fastened to a frame.
