Abstract
A sensor device for detecting mechanical deformation of a component, in particular in the automotive field, has a deformation device, which has a deformable polysilicon part that undergoes a change in electric resistance in deformation; and an electric line arrangement for analog transmission of the change in resistance data of the polysilicon part from the deformation device to a central unit.
Claims10
A sensor device for detecting a mechanical deformation of a component, comprising:
- a central unit;
- a deformation device including a deformable polysilicon part which undergoes a change in electric resistance in response to a deformation;
- and
- an electric conductor arrangement for analog transmission of change-in-resistance data of the polysilicon part from the deformation device to the central unit;
- wherein the polysilicon part is a polysilicon strain gauge that is wired as a rheostat.
