An actuator mechanism for a body is disclosed. The actuator mechanism has at least one actuator produced from an electro-active polymer material that changes form due to electrical energy, thereby actuating the body The actuator mechanism also has at least two strengtheners allowing the actuator to change its form, each holding the actuator from a different side, and positioned oppositely on the body The actuator mechanism further has at least one retainer tip holding the actuator from at least one side thereof.
