Abstract
A device including a piezoelectric actuator that can detect the actuation force and provide haptic feedback. The longitudinal extension of the actuator, generated for this purpose, can be reinforced in the desired direction by a deformable metal sheet. The deformable metal sheet is adhered on and has a borehole for pressure equalization.
