Abstract
A tactile transmission device for transmitting a tactile sensation to a user's finger comprises: a ring-type body which is put on a finger; a moving member which is formed such that the moving member can move with respect to the body; and a plurality of wire-type actuators which are formed so as to come in contact with the moving member, wherein each of the wire-type actuators is a solid-state actuator which changes in length when energy is applied thereto, a force applied to the moving member as the plurality of wire-type actuators change in length causes the moving member to move with respect to the body, and a contact part formed in the moving member comes into contact with a user's finger according to a movement of the moving member, so as to transmit a tactile sensation to the user.
