Abstract
A piezoelectric drive (1) with an inner part (2) that is surrounded by an outer part (3). The inner part (2) includes at least one piezoelement (9) that is actively connected to an oscillation element (5). The oscillation element (5) has a middle part (6) about which at least one arm (7, 15) is arranged. The arm is actively connected to the outer part (3) via an interaction region (16) and is designed such that, when set into oscillation by way of the at least one piezoelement (9), it drives the outer part (3) relative to the inner part (2).
