Abstract: An actuation device includes a Peltier comprising a first side and a second side; a first module thermally coupled to the first side of the Peltier, and a second module thermally coupled to the second side of the Peltier. The first module is configured to axially contract in response to an increased pressure within the first module and axially expand in response to a decreased pressure within the first module. The second module is configured to axially expand in response to an increased pressure within the second module and axially contract in response to a decreased pressure within the second module.

Abstract: An actuator includes an output link; an input member, wherein the output link and the input member are rotatable about an axis of rotation; an elastic member disposed between the output link and the input member and configured to allow transmission of torque between the output link and the input member about the axis of rotation, and to allow at the same time, as a result of elastic deformation of the elastic member, a relative rotation between the output link and input member about the axis of rotation; and a thermo-active module comprising one or more thermoplastic inserts, wherein the thermoplastic inserts are configured to apply a variable resistance between the output link and the input member and provide an adjustable damping between the output link and the input member.

Abstract: A device includes a flexible Peltier; a power supply in electrical communication with the flexible Peltier; a control switch electrically coupled to the power supply and the flexible Peltier. The control switch is configured to control direction of current supplied from the power supply to the flexible Peltier, and at least one flexible layer is coupled to the flexible Peltier. The at least one flexible layer is configured to retain the flexible Peltier about a portion of a subject.

Abstract: A device can include at least one of an exoskeleton comprising a preloaded elastic spring, a plurality of drums coupled to the preloaded elastic spring, and a cable coupled to a user, the plurality of drums and the preloaded elastic spring; and a robotic hand. The robotic hand includes a glove comprising digits, a tubing system in fluid communication with a fluid supply, a plurality of sensors coupled to the digits of the glove, and a plurality of soft actuators coupled to the tubing system and the plurality of sensors. The plurality of soft actuators comprises a thickened base, a fluid cavity above the thickened base defined by a tube, and a retaining device wrapped around the tube.
