A handle includes a housing that includes a first vibrating body and a second vibrating body. A control device is able to generate a first force sensation in a first direction by controlling a vibration pattern of the first vibrating body and to generate a second force sensation in a second direction by controlling a vibration pattern of the second vibrating body. The control device is able to control so as to set the first direction and the second direction are the same. The control device is able to control the vibration pattern of the first vibrating body and the vibration pattern of the second vibrating body so as not to allow a virtual line directed from the first vibrating body in the first direction and a virtual line directed from the second vibrating body in the second direction to be positioned on a single line.

A hair straightening device including a first arm, a hinge connected to the first arm, and a second arm connected to the hinge. The first arm, the second arm, or both are rotatable around the hinge between an open position where the first arm and the second arm do not contact each other and a closed position where the first arm and the second arm contact each other. The second arm comprises protrusions extending away from an interior surface of the second arm that faces the first arm of when the hair straightening device is in the closed position. The first arm may include holes corresponding to the protrusions, a first deformable material that is contacted and deformed by the protrusions, a first non-deformable material that is contacted but not deformed by the protrusions, or a combination thereof.

A hair styling appliance is described having a pair of electrodes, a chamber located between the electrodes for receiving a section of hair, and a drive unit for applying an alternating voltage to the electrodes to heat the hair dielectrically. The electrodes have a fixed spacing.

A hair styling appliance is described having a pair of electrodes, and a drive unit for applying an alternating voltage to the electrodes to heat dielectrically hair located between the electrodes. The drive unit includes mutually coupled inductors having a coupling coefficient that varies in response to changes in a spacing of the electrodes.

The appliance also has a pair of arms having an open position and a closed position. The arms grip the hair when in the closed position, and the chamber has a height of between 1 mm and 10 mm when the arms are in the closed position.

A hair-styling device serves to curl or wave hair. Said hair-styling device comprises two styling bodies 5, 5.1, which interact with each other to style the hair and can be rotated about the longitudinal axis of the styling bodies and of which at least one of the styling bodies 5, 5.1 is driven, which styling bodies 5, 5.1 have a shell surface contoured by elevations and recesses and are arranged in relation to each other in such a way that complementary contours of the two styling bodies 5, 5.1 mesh in the course of rotation of the two styling bodies. The styling bodies 5, 5.1 have a bone-shaped cross-sectional geometry having two head sections 7, 7.1 designed with a shell surface 8 that is convexly rounded at least in some sections and having a tapered central section 6 located between the head sections and designed with a concave shell surface. The radius of curvature in the region of the central apex 9 of the head sections 7, 7.1 of the one styling body 5, 5.1, 5.2 corresponds to the radius of curvature of the tapered central section 6 of the other styling body. The axis of rotation 11, 11.1 of the styling bodies (5, 5.1) is arranged in the central section 6 centrally between the central apexes 9 of the head sections 7, 7.1.
