Abstract (en)
[origin: WO2019170483A1] A device for measuring mechanical changes comprises at least one first resistor, which is designed to convert a mechanical change into an adjustment of its resistance value; and at least one operational amplifier, wherein the at least first resistor and the operational amplifier are connected such that the at least first resistor serves the operational amplifier as an input resistance and the operational amplifier provides or can provide a measurement result at an output. The first resistor is e.g. a strain gauge which can be secured on a component.
