Abstract: Provided is a wearable suit. The wearable suit includes: a device part provided with springs made of shape memory alloy; shoulder straps coupled to allow a wearer to shoulder the device part; an abdominal fixation part configured to allow the device part to be worn on the wearer's abdomen; and lower extremity belts coupled to a wire exposed from the device part. The springs assist in pulling out the wire exposed from the device part by contracting and expanding in response to supplied power. The device part may include an upper terminal configured therein. A first wire may be configured to extend from the upper terminal. The other end of the first wire may be coupled to a support member. First ends of the plurality of springs made of shape memory alloy may be arranged on the other side of the upper terminal.
