Abstract: A soft haptic device and a local control method are disclosed. The soft haptic device includes a soft actuator. The soft actuator includes an electroactive polymer film, a patterned electrode, and a dielectric liquid injected between the electroactive polymer film and the patterned electrode. The soft actuator generates a reconfigurable shape such that a form of an output shape and a number of outputtable shapes are changed depending on the number of electrodes constituting the patterned electrode, a shape of the electrodes, and an arrangement of the electrodes.

Abstract: Disclosed is a wearable robot for assisting a wrist, including: a plurality of flexible actuators; and a control unit configured to control any one of the plurality of flexible actuators to be contracted or relaxed according to a wrist movement of a wearer. Each of the plurality of flexible actuators includes: a driving part which is contractively deformed by a current or transfer heat applied from the control unit or is relaxed when the heat is lost, and a refrigerant circulating part which is implemented to surround the driving part and circulates a refrigerant so that the contractively deformed driving part is cooled under control of the control unit.
