Abstract:
1. A wearable human motion applicator comprising: a support adapted to be fitted on a part of a human body; at least one electro-active elastic actuator carried by said support in a force-transmitting relation to said part of the human body, said elastic actuator including a dielectric core and a pair of electrodes on opposite surfaces of said core configured to receive a driving DC voltage thereacross, said elastic actuator having a length and elastically expanding in a lengthwise direction and therefore exerting a stretching force to said part of the human body to a greater extent as said driving DC voltage increases; a DC voltage source configured to provide said driving DC voltage; a controller configured to apply said driving DC voltage of varying levels to said elastic actuator, thereby generating a varying motion-inducing force to be applied to said part of the human body; and a signal generator configured to generate a random signal indicative of the driving DC voltage varying randomly, wherein: said controller applies to said elastic actuator the driving DC voltage which varies randomly in accordance with the random signal.
