    Abstract: A seating system includes a seat, with structures for supporting a user thereon, and actuators. Each actuator includes a deformable shell with an enclosed internal cavity containing a fluid dielectric contained, a pair of electrodes disposed on opposing sides of the deformable shell. The actuators are integrated into the structures and configured for providing at least one function, such as haptic feedback, seat adjustment, alert notification, vibratory signal, user input receiving, and massage function. A portion of the plurality of actuators may be enclosed within an encapsulating shell to form an encapsulated sheet of actuators. Each actuator may be a part of a button-on-demand system, wherein the actuator is normally in a collapsed position such that a user-facing surface of the encapsulating shell is substantially flat and, when activated by a user, the actuator is configured to expand such that the encapsulating shell is raised to form a button.

    Abstract: The present disclosure describes new systems and methods for influencing the rotational speed of a roller or other conveying systems and for controlling the speed, orientation or position of objects on a conveyor through the use of hydraulically amplified self-healing electrostatic (HASEL) actuators. HASEL actuators for such systems provide distinct benefits over traditional braking systems including: electrical control, eliminated need for an external source of pressurized air or fluid to allow use in certain environments, analog control of force or displacement in order to provide variable control of speed of objects on the conveyor system, and feedback to infer information about the state of the actuators as well as the state of objects being conveyed and/or state of the conveyor rollers.
