A stimulation device includes a base body, and a contact element attached on or in the base body, for contact with a body part of the user. The contact element has a reversibly deformable contact surface region. A shaping element, to generate a local deformation of the contact element without deforming the base body, is arranged on or in the base body to move in relation to the base body. An actuation device is arranged on or in the base body and operatively connected to the shaping element to generate movement of the shaping element. The actuation device comprises a shape-memory element that can be deformed by applying an electrical current and/or a magnetic field and/or by changing the temperature, and is connected to the base body on one side and to the shaping element on the other side, and, by deforming, causes a movement of the shaping element.
