More Information
Summary:According to one embodiment of the present invention, a flexible tactile actuator capable of providing various tactile senses to a user may comprise: a tactile transfer unit including magnetic particles capable of polarization in response to an external magnetic field and a matrix layer containing the magnetic particles, wherein the tactile transfer unit can be bent; a magnetic field generation unit located below the tactile transfer unit and generating a magnetic field in the tactile transfer unit; and a film-shaped elastic member fixed so that at least a part of the elastic member is in surface contact with an upper surface of the magnetic field generation unit and in surface contact with one of an upper surface and a lower surface of the tactile transfer unit. 일 실시 예에 따른 플렉시블 촉각 액추에이터는, 외부 자기장에 반응하여 분극이 가능한 자성입자 및 상기 자성입자를 함유하는 매트릭스 레이어를 포함하고, 휘어질 수 있는 촉각 전달부; 상기 촉각 전달부의 하방에 위치하고, 상기 촉각 전달부에 자기장을 발생시키는 자기장 생성부; 및 적어도 일부가 상기 자기장 생성부의 상면에 면 접촉하고, 상기 촉각 전달부의 상면 및 하면 중 어느 하나의 면과 면 접촉하도록 고정되는 막 형상의 탄성 부재를 포함할 수 있다.
