Claim:
1. An actuator unit for an injection valve of an internal combustion engine of a vehicle, comprising: an electronic component in the form of a stack, with a piezoelectric sensor comprising a sensor body and two outer sensor electrodes disposed on opposite end faces of the sensor body, wherein one of the two outer sensor electrodes of the piezoelectric sensor is coupled to the component through an insulation layer in a force-fit manner in the stroke direction of the component, and the piezoelectric sensor detects a force generated and applied to the one of the two outer sensor electrodes by movement of the component during operation of the component, the force applied to the one of the two outer sensor electrodes being detected as a voltage or charge between the two outer sensor electrodes, wherein the two outer sensor electrodes are comprised of electrically conductive material deposited directly onto at least one of the end faces of the sensor body.
