Abstract
A piezo actuator (,) is disclosed that has a contact lug (,) for the electrical contacting of an electrode (,) of an actuator member (,). Due to an expansion and contraction of the actuator member, a mechanical stress occurs in the contact lug that is minimized in that the contact lug has a device for adapting the expanse to a dimension of the expansion and contraction. The device is, for example, a deformation material in the form of a wire weave. The piezo actuator is utilized for the drive of an injection valve in an internal combustion engine.
