Stimulation device with change of shape using shape-memory element

A stimulation device, comprising:

• a base body, and a contact element which is mounted on or in the base body, for contact with a body part of a user and having at least one reversibly deformable contact surface region, wherein at least one shaping element to generate a local deformation of the contact element without deforming the base body, is arranged on or in the base body so as to be movable in relation to the base body, and at least one actuator is arranged on or in the base body and is operatively connected to the at least one shaping element in order to generate a movement of the at least one shaping element, which actuator comprises at least one shape-memory element deformable by application of an electric current and/or of a magnetic field and/or by change of temperature, which shape-memory element is connected at one end to the base body and at the other end to the at least one shaping element and, by deformation, causes a movement of the at least one shaping element.
