Abstract

An appendage pressurization device includes an appendage strap and one or more artificial muscles disposed in the appendage strap and communicatively coupled to a controller. Each artificial muscle includes a housing comprising 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 comprising a first electrode fixed to a first surface of the housing and a second electrode fixed to a second surface of the housing, wherein the electrode pair is actuatable between a non-actuated state 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. The appendage pressurization device also includes a pressure sensor communicatively coupled to the controller, wherein the pressure sensor is configured to output a current pressure value to the controller and actuation of the electrode pair is based on the current pressure value.
