DIFFERENTIAL STRAIN GAGE – A NEW SENSOR DEVICE FOR MICROSYSTEMS

• Abstract:

  The paper describes an operating principle for the electrical measurement of mechanical strain states. This principle gives up the idea of measuring the strain-induced resistance change of single wire conductors and passes on to determining the strain-induced deformation of the electrical field in area conductors. The basic operating principle, sensitivity considerations and the design of a functional prototype are described. Several experimental results in the application fields of transducer technology demonstrate the high capability of this method.
