Abstract
A pen-shaped input and/or output device and a method for generating a haptic signal are disclosed. In an embodiment a device includes an actuator unit that has 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.
