  • Appendage massaging devices comprising artificial muscles
    Patent number: 11986439
    Abstract: An appendage massaging device that includes an appendage wrap having an inner band and an outer layer and one or more artificial muscles disposed between the inner band and the outer layer of the appendage wrap. Each of the one or more artificial muscles include a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair positioned in the electrode region of the housing. The electrode pair includes a first electrode fixed to a first surface of the housing and a second electrode fixed to a second surface of the housing. The electrode pair is actuatable between a non-actuated and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region thereby applying pressure to the inner band of the appendage wrap.
