Abstract
In an embodiment a shape-transformable switch apparatus includes an electromagnet arranged inside a housing, wherein the electromagnet has an outer circumferential surface wound with a solenoid coil and is configured to provide a magnetic field when a power is applied to the solenoid coil, a Magnetorheological Elastomer (MRE) disposed on an upper portion of the electromagnet, wherein the MRE is configured to change from an initial soft state to a relatively hard state when the power is applied to the solenoid coil and configured to be pressed and to move upward when the electromagnet moves upward and a switch cover disposed on an upper portion of the housing, the switch cover configured to form a switch shape and to protrude outward when the MRE moves in an upward direction.
