A seat that includes an upper surface, a lower surface, one or more pressure sensors communicatively coupled to a controller, and a plurality of artificial muscles disposed between the upper surface and the lower surface. Each of the plurality of artificial muscles is communicatively coupled to the controller. Each of the plurality of artificial muscles includes 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 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.

A representative system includes a personal transportation device with: first and second wheels aligned along an axis; an idler wheel rearward of the axis; a platform configured to support a user in a standing position; electric motors to drive the first and second wheels; first and second hand grips fixed in position at respective locations forward of the platform; and first and second control actuators disposed, respectively, on the first and second hand grips, the first and second control actuators being operative to control rotations of the first and second wheels and configured to be actuated by corresponding thumbs of the user while hands of the user are grasping corresponding ones of the first hand grip and the second hand grip.

A manufacturing method of a seating device includes manufacturing an outer skin; manufacturing a core member via a foaming process; wrapping the core member in the outer skin, coupling a mounting plate at a bottom surface of the core member; and selectively coupling a mounting structure to the mounting plate to form the seating device. The outer skin is constructed to have a top skin layer adhered on a top surface of the core member, a side skin layer adhered on a side surface of the core member, and a bottom skin layer adhered on a bottom surface of the core member. Particularly, the top skin layer of the outer skin is adhered on the top surface of the core member edge-to-edge to initially align and retain the outer skin on the core member.

A bicycle seat assembly that is configured to be attached to a frame of a bicycle includes a seat pan, a foam layer, and an air cell pad. The seat pan is configured to be attached to the frame of the bicycle. The seat pan includes a pair of cutouts that are spaced apart from one another. The air cell pad includes a base and a plurality of upstanding air cells that are coupled to the base, each of the plurality of air cells being configured to retain air. The foam layer can be positioned between the air cell pad and the seat pan; or the air cell pad can be positioned between the foam layer and the seat pan.

An adjustable saddle may include a first saddle half that may be slidably adjustable to a front mounting assembly and slidably adjustable to a rear mounting assembly. An adjustable saddle may further include a second saddle half that may be slidably adjustable to a front mounting assembly and slidably adjustable to a rear mounting assembly. Additionally, the attachment features may be configured to be releasably securable to the mounting assemblies. The first saddle half and the second saddle half may be adjusted independently of each other to adapt to a given sit bone width and riding position to achieve maximum comfort.
