摘要： At least some embodiments of the present disclosure an electrostatic sheet jamming device comprising a first sheet having a first conductive layer, a first dielectric layer disposed adjacent to the first conductive layer, and a second sheet comprising a second conductive layer and disposed proximate to the first dielectric layer. The first dielectric layer is disposed between the first conductive layer and the second conductive layer. The first sheet and the second sheet are non-extensible and flexible, wherein the first sheet and the second sheet are slidable relative to each other in a first state. The first sheet and the second sheet are jammed with each other in a second state when a voltage is applied between the first conductive layer and the second conductive layer. In some embodiments, the applied voltage is less than or equal to a break-down voltage of air at a distance between the first conductive layer and the second conductive layer.

摘要： Described are methods for manufacturing and using an electromechanical soft actuator including a dielectric liquid crystal elastomer. A method for manufacturing the electromechanical soft actuator including the dielectric liquid elastomer may include the steps of fabricating a loosely cross-linked polydomain liquid crystal elastomer, pre-stretching the loosely cross-linked polydomain liquid crystal elastomer on a frame, cross-linking elements of the loosely cross-linked polydomain liquid crystal elastomer to form the dielectric liquid crystal elastomer and removing the frame from the dielectric liquid crystal elastomer. The disclosed electromechanical soft actuator including the dielectric liquid crystal elastomer can be used in transducer for converting electrical energy to mechanical energy. The transducer may include at least two electrodes, and the dielectric liquid crystal elastomer, which has a first position that is deflected to a second position in response to a change in an electric field provided by the at least two electrodes.

摘要： 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.

摘要： A micro-electro-mechanical system (MEMS) device may comprise a first layer that includes a stator comb actuator; a second layer that includes a rotor comb actuator; a mirror structure that includes a mirror; and a first set of hinges and a second set of hinges configured to tilt the mirror structure about a first axis of the MEMS device based on a driving torque caused by the stator comb actuator engaging with the rotor comb actuator. The first set of hinges may be configured to resist a lateral linear force on the mirror structure in a direction associated with the first axis caused by the stator comb actuator engaging with the rotor comb actuator. The second set of hinges may be configured to resist an in-plane torque on the mirror structure about a second axis of the MEMS device caused by the stator comb actuator engaging with the rotor comb actuator.
