Abstract: Techniques relating to a micro-electro-mechanical (MEMS) device configured to measure direct axial and shear stress components of a stress tensor are described. The MEMS device includes a first and second circuit configured in a double rosette structure coupled with a third circuit in a standard rosette structure to form a triple rosette piezo-resistive gauge circuit. The first circuit includes at least one piezoresistive element suspended from a substrate, and at least one piezoresistive element fixed to the substrate. The second circuit includes each piezoresistive element fixed to the substrate. The third circuit includes at least one piezoresistive element fixed to the substrate. Additionally, the MEMS device may be coupled to one or more processing systems to determine a mechanical stress tensor that is applied to the MEMS device based on measurements received from the MEMS device.

Abstract: A sensor arrangement for measuring at least one component of a force or a torque includes a sensor assembly having a first contact structure and a second contact structure, between which the at least one component of the force or torque is to be measured, and a plurality of sensor elements. The plurality of sensor elements are each connected by way of a first joint to the first contact structure and by way of a second joint to the second contact structure and configured to measure the component of force or torque between the first contact structure and the second contact structure. The first contact structure, the second contact structure and the plurality of sensor elements form a rolled-up structure that extends like a jacket along a surface of the sensor arrangement.
