Patent ID: 6909220

Claim:
A artificial muscle actuator comprising: a) one or more thin film layers folded or rolled into the shape of a cylinder forming a center part of said cylinder and an outer part of said cylinder, said film layer having a top surface Mn 1 and a bottom surface Mn 2 , said top surface and said bottom surface each coated with an electrical conducting layer Mc, said conducting layer of said top surface connected by a first electrode on said top surface positioned at said center part and said bottom surface connected by a second electrode on said bottom surface positioned at said outer part; said first and second electrodes being connected to one or more direct current power source or sources, said power supply capable of generating a electrical potential of a positive electrical charge to the first electrode and a negative electrical charge to the second electrode from less than about 100 volt to above about 10,000 volts; said film layers comprising a gel made from one or more copolymers having one or more polyethylene segments and capable of exhibiting crystallinity at about 10° C. and higher as determined by differential scanning calorimetry curve, said gel having rigidities of from less than about 2 gram Bloom to about 1,800 gram Bloom; and said gel being capable of exhibiting greater tear resistance than amorphous gels of poly(styrene-ethylene-propylene-styrene).
