  • ARTIFICIAL MUSCLES COMPRISING AN ELECTRODE PAIR AND ARTIFICIAL MUSCLE ASSEMBLIES INCLUDING SAME
    Publication number: 20220243743
    Abstract: An artificial muscle that includes a housing having an electrode region and an expandable fluid region and an electrode pair positioned in the electrode region, the electrode pair having a first electrode fixed to a first surface of the housing and a second electrode fixed to a second surface of the housing. The first and second electrodes each have two or more tab portions and two or more bridge portions. Each of the two or more bridge portions interconnects adjacent tab portions and at least one of the first and second electrodes includes a central opening positioned between the two or more tab portions and encircling the expandable fluid region. A dielectric fluid is housed within the housing and the electrode pair is actuatable between a non-actuated and an actuated state such that actuation from the non-actuated to actuated state directs the dielectric fluid into the expandable fluid region.
    Type: Application
