US Patent 11370340 Systems and methods for actuating pillows including actuating muscles

An actuating pillow includes a pillow body and a plurality of artificial muscles arranged within the pillow body. Each of the artificial muscles includes a housing having an electrode region and an adjacent expandable fluid region, an electrode pair positioned in the electrode region of the housing, and a dielectric fluid housed within the housing. The plurality of artificial muscles are configured to actuate from a non-actuated state to an actuated state, actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region and increases a height of the pillow body.
