摘要: An actuator that includes a shell, a ring structure within the shell, a shape-memory material wire fixed at opposite points of the ring structure to extend in a first direction across a width of the ring structure, and a cooling fluid provided within the shell and in fluid communication with the shape-memory material wire. When the shape-memory material wire is heated, the shape-memory material wire contracts in the first direction to reduce the width of the ring structure and increases a height of the ring structure extending in a second direction perpendicular to the first direction.

摘要: An artificial muscle includes a housing including an electrode region, an expandable fluid region, a first film layer, and a second film layer. The first film layer and the second film layer each include an inner protective layer having a first elasticity, an outer protective layer having a second elasticity, and a reinforcing layer provided between the inner protective layer and the outer protective layer, the reinforcing layer having a third elasticity greater than the first elasticity of the inner protective layer and the second elasticity of the outer protective layer. The artificial muscle further includes an electrode pair positioned in the electrode region of the housing and between the first film layer and the second film layer, and a dielectric fluid housed within the housing.

摘要: An artificial muscle assembly includes initiating actuators and an artificial muscle. The artificial muscle includes a housing including an electrode region and an expandable fluid region, and an electrode pair positioned in the electrode region. The electrode pair includes a first electrode and a second electrode fixed to respective first and second surfaces of the housing. At least one of the first electrode and the second electrode includes a central opening defining the expandable fluid region. 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 a dielectric fluid into the expandable fluid region. Each initiating actuator is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state applies a force against the electrode region of the artificial muscle.

摘要: A hybrid actuation device including an artificial muscle is disclosed. The artificial muscle includes a housing including a first reinforcing thread extending across an expandable fluid region of the housing, an electrode pair positioned in an electrode region of the housing, and a dielectric fluid housed within the housing. The electrode pair includes a first electrode positioned adjacent a first surface of the housing and a second electrode positioned adjacent a second surface of the housing. 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. The first reinforcing thread restricts expansion of the expandable fluid region when the electrode pair is in the actuated state.

摘要: An artificial muscle that includes a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, an electrode pair positioned in the electrode region of the housing, the electrode pair including a first electrode and a second electrode, and an electrode insulator having one or more insulation layers. The electrode insulator is disposed on an inner electrode surface of the first electrode of the electrode pair. The second electrode includes a free inner electrode surface exposed to the dielectric fluid when the electrode pair is in a non-actuated state. The electrode pair is actuatable between the 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.

摘要: An artificial muscle drive unit includes a base and an artificial muscle disposed on the base. The artificial muscle includes an expandable reservoir and a fluid. The fluid is movable within said expandable reservoir to switch the artificial muscle between a non-actuated state in which a dimension of the artificial muscle in a movement direction is a minimum value, and an actuated state, in which the dimension of the artificial muscle is a maximum value. The artificial muscle drive unit also includes a load-bearing support disposed on the base, the load-bearing support comprising a dimension in the movement direction that is greater than or equal to the minimum value.
