Abstract
According to an embodiment, a device comprises: a piezoelectric element configured to convert an electrical voltage into a mechanical strain; and a conductive base plate onto which the piezoelectric element is fastened, wherein the conductive base plate comprises an integrated support positioned on an underside of the conductive base plate, wherein the conductive base plate is supported by the integrated support; wherein the device is configured to provide haptic feedback on a basis of the mechanical strain.
Claims13
A device, comprising:
- a piezoelectric element configured to convert an electrical voltage into a mechanical strain, wherein an electrode is fastened to a top surface of the piezoelectric element;
- a conductive base plate onto which the piezoelectric element is fastened, wherein the conductive base plate is configured as a lower electrode of the piezoelectric element,
- wherein the conductive base plate comprises an integrated support positioned on an underside of the conductive base plate, wherein the integrated support is formed into the conductive base plate by punching or by bending edges of the conductive base plate;
- and
- a carrier layer, wherein the conductive base plate lies on the carrier layer and the conductive base plate is supported by the integrated support;
- wherein the device is configured to provide haptic feedback on a basis of the mechanical strain.
