An artificial muscle system includes an artificial muscle and a power supply. The artificial muscle includes an electrode pair including a first electrode and a second electrode, an electrical insulator membrane fixed to the second electrode, a housing including an electrode region and an expandable fluid region, the electrode pair positioned in the electrode region of the housing, and a dielectric fluid housed within the housing. The power supply includes a positive terminal and a negative terminal. The positive terminal is electrically coupled to the second electrode. The negative terminal is electrically coupled to the first electrode. 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.

A plurality of actuators can be operatively positioned to cause a movement of the seat portion. The actuators can include one or more shape memory material members. Each of the actuators being configured such that, when an activation input is provided to the one or more shape memory material members, the one or more shape memory material members change from a first configuration to a second configuration and cause the actuator to morph into an activated configuration. One or more processors operatively connected to selectively activate one or more of the actuators by causing the activation input to be provided to the one or more shape memory material members of at least one of the actuators.

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.

An actuator can include one or more shape memory material members. When an activation input is provided to the one or more shape memory material members, the one or more shape memory material members contract, which causes the actuator to morph into an activated configuration. A height of the actuator increases in the activated configuration. The actuator can include a first outer body member and a second outer body member. The first outer body member can include a first portion and a second portion pivotably connected to each other. One or more processors can be operatively connected to selectively activate the one or more shape memory material members.
