Tactile device

The invention refers to a tactile device provided with a number of fluid elements ( 1 ) containing an electrically conducting fluid ( 3, 4 ). The fluid level in each element is movable by actuator means (V, 6 ) applying a electric power to said fluid elements. Each fluid element is at one end provid...

Beschreibung
Zusammenfassung:	The invention refers to a tactile device provided with a number of fluid elements ( 1 ) containing an electrically conducting fluid ( 3, 4 ). The fluid level in each element is movable by actuator means (V, 6 ) applying a electric power to said fluid elements. Each fluid element is at one end provided with a tactile element ( 7 ) that is in contact with the fluid for perception of the fluid level by a user. The fluid elements comprise capillary tubes ( 2 ) in which the fluid level is movable as a result of electro-capillary pressure.
