  • Patent number: 11653569
    Abstract: A device having a piezoelectric actuator, which can both detect the actuation force and provide a haptic feedback. The linear expansion of the actuator can be amplified in the desired direction by a deformable metal sheet. The actuator has a flat piezoelectric basic body having plane-parallel main surfaces and two electrodes. The body is designed to generate an active haptic feedback when a force exerted upon the basic body is detected. The haptic feedback is generated in that an actuator voltage, which, by piezoelectric actuator action, results in a change in the length of the basic body, is applied between the electrodes. A cymbal-shaped metal sheet is fastened to the basic body. The body is fixed with the truncated cone vertices between a base and an actuation means connected to the base and fixed by means of a bias, which is set as tensile or compressive stress.
