Abstract: A system for sensing torque of an object includes a flange having a first length along a main axis of a main surface of the flange and a torque sensor device formed over the main surface of the flange. The torque sensor device includes a sensing portion and a plurality of measurement transducers formed over the sensing portion. The torque sensor device has a second length parallel to the main surface of the flange and a third length parallel to the main surface of the flange. The second length and the third length are each smaller than half of the first length.

Abstract: A sensing membrane includes a first main surface forming a top of the sensing membrane, a plurality of measurement transducers formed over the first main surface, a second main surface opposite to the first main surface and forming a bottom of the sensing membrane, and a thickening element formed below the second main surface opposite to the measurement transducers.

Abstract: A torque sensor device includes a circular body having an annular inner flange, an annular outer flange, and a circular intermediate portion between the annular inner flange and the annular outer flange. The annular inner flange is closer to a center of the circular body than the annular outer flange. The circular intermediate portion is a continuously solid portion.
