1. A wireless actuation system, the system comprising
a device for wireless actuation, the device comprising:
a bladder having an inner surface and an outer surface, the inner surface forming an interior area, the bladder configured to expand or retract so as to change an area of the interior area;
a plurality of magnetic particles suspended in a fluid medium and disposed within the interior area, the plurality of magnetic particles configured to react to an alternating magnetic field which causes a phase transition to the fluid medium within the interior area and causes the bladder to expand; and
a sleeve disposed on the outer surface of the bladder, the sleeve configured to confine the bladder so as to generate actuation from the expansion or retraction of the bladder; and
a magnetic field generator configured to generate an alternating magnetic field.
