Abstract
In a piezoelectric drive comprising clamping piezo packets which are adjacently arranged, under compressive pre-stress, between a reference part and an output part, the reference part is connected to the clamping piezo packets by means of a 'semi-rigid' bridging plate, which adapts in a flexible manner to differences in stack height of the piezo packets, in a static state but remains essentially rigid in a dynamic state, that is, at the operating frequency of the drive.
