摘要： A hydraulic actuator device for a hydraulic system filled with an electrically conductive medium, the hydraulic actuator device being situatable or being situated on and/or in the hydraulic system, and including at least one actuator module, which in each case is designed in such a way that at least a portion of the electrically conductive medium is acceleratable into at least one partial volume of the hydraulic system due to its interaction with an electrical current flow generated with the aid of the respective actuator module and/or with a magnetic field created with the aid of the respective actuator module, as a result of which a pressure build-up is creatable in the at least one partial volume of the hydraulic system.

摘要： High strain hydraulically amplified self-healing electrostatic transducers having increased maximum theoretical and practical strains are disclosed. In particular, the actuators include electrode configurations having a zipping front created by the attraction of the electrodes that is configured orthogonally to a strain axis along which the actuators. This configuration produces increased strains. In turn, various form factors for the actuator configuration are presented including an artificial circular muscle and a strain amplifying pulley system. Other actuator configurations are contemplated that include independent and opposed electrode pairs to create cyclic activation, hybrid electrode configurations, and use of strain limiting layers for controlled deflection of the actuator.

摘要： Hydraulically-amplified, self-healing, electrostatic transducers that harness electrostatic and hydraulic forces to achieve various actuation modes. Electrostatic forces between electrode pairs of the transducers generated upon application of a voltage to the electrode pairs draws the electrodes in each pair towards each other to displace a liquid dielectric contained within an enclosed internal cavity of the transducers to drive actuation in various manners. The electrodes and the liquid dielectric form a self-healing capacitor whereby the liquid dielectric automatically fills breaches in the liquid dielectric resulting from dielectric breakdown. Due to the resting shape of the cavity, a zipping-mechanism allows for selectively actuating the electrodes to a desired extent by controlling the voltage supplied.

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.

摘要： 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.

摘要： Apparatuses for flowing multiple fluids in a single channel while substantially maintaining fluid separation are disclosed. In one configuration, the apparatus includes a first internal surface portion with an affinity to a first fluid and a second internal surface portion with an affinity to a second fluid. In another configuration, the apparatus includes a first fluid channel portion, a second fluid channel portion wrapped helically around the first fluid channel portion, and an opening therebetween. Also disclosed is an apparatus for maintaining substantially even fluid flow in fluid pathways having a first flow resistor portion, a second flow resistor portion, and a fluid channel therebetween.
