Abstract
An actuation device () which includes an actuation element () with a fixed 10 portion () and a driving portion (); wherein the fixed portion () includes a crawling surface (). The driving portion () includes a flexible moveable blade () positioned in parallel and at a distance from the crawling surface (). When a power supply voltage is applied between the moveable blade () and the crawling surface (), the free end () comes into contact with the crawling surface (), and a contact area, between the moveable blade () and the crawling surface (), increases by propagation of the crawling front () along the moveable blade (). The propagation of the crawling front displaces the moveable blade () according to a first orientation.
