Abstract
Disclosed is an integral self-monitoring soft actuator including a body portion configured to be driven by deformation due to stimulation; a first limiter integrally formed with respect to the longitudinal direction of the body portion to limit deformation of the body portion in the longitudinal direction; a second limiter that limits deformation of the body portion in the radial direction by including at least a pair of electrodes in a spiral shape integrally provided on the outer surface of the body portion; and a controller for controlling motion of the body portion, wherein the controller self-monitors deformation of the body portion by self-sensing changes in the intervals between the electrodes according to deformation of the body portion. According to the above configuration, deformation of the body portion may be self-detected in real time using the second limiter integrally provided with the body portion, thereby improving control efficiency.
