1. A vehicle interior trim element with haptic feedback function, comprising:
an elastic base layer configured to give the vehicle interior trim element a soft feel,
a flexible cover layer comprising an electrically insulating upper layer disposed on a visible side of the vehicle interior trim element, an electrically conductive sensor layer disposed between the upper layer and the base layer, a piezoelectric actuator layer disposed between the sensor layer and the base layer, wherein
the sensor layer is configured to detect a contact of the upper layer without deformation and to locate a corresponding contact area, and wherein
the actuator layer is configured to provide haptic feedback.
