1. A device comprising:
an actuator unit comprising a piezoelectric actuator,
wherein the device is a pen-shaped input and/or output device,
wherein the pen-shaped input and/or output is configured to use the piezoelectric actuator as a sensor,
wherein the piezoelectric actuator is configured to generate a voltage as a result of an actuation of the pen-shaped input and/or output device, and
wherein the pen-shaped input and/or output device has a second electronics circuit configured to detect the voltage generated by the piezoelectric actuator and store a characteristic value for the voltage generated.
