Evaluating Thermo-Mechanical Stress Due to Surface Grinding on a Sensor Integrated Workpiece

M. Sarma [1], M. Reimers, G. Dumstorff [1], W. Lang [1]
[1] Institute for Microsensors, -Actuators and –Systems (IMSAS), University of Bremen, Dept. 1: Physics / Electrical Engineering, Germany

Sensor integration in a workpiece can be used to characterize manufacturing processes but due to integration, a foreign element is added to the material which can alter its material properties [1]. This can lead to a high order of measurement uncertainty. Additionally, the extent of ... En savoir plus
