Abstract: Disclosed herein is a soft wearable driving system including a body part formed of a deformable flexible material and having a shape extending in a plane, the body part being deformed in a manner of at least one of tensioning, compression, or bending in response to a magnitude of a load voltage, a sensor arranged on one side of the body part of the flexible material to sense a level of muscle activity in an installation area of the body part on the human body, and a controller configured to control the load voltage of the body part based on information sensed by the sensor. In this configuration, a lightweight system that provides high power for long periods of use may be provided, thereby improving usability.
