摘要： Fluidic artificial muscle device comprising at least one pleated actuator (1 ) adapted to exert forces along an axis (K). Said actuator (1 ) comprises a chamber (10) delimited by closing portions (11) at the two opposite ends along said axis (K) and a flexible membrane (13) in the central portion (12) interposed to said closing portions (11). The membrane (13) has a plurality of ridges (130) and valleys (131) that alternate with each other in a circumferential direction around said axis (K) to form a pleated structure. Said actuator (1 ) consists of a single

摘要： A soft vine robot includes a main body configured as a tube inverted back inside itself to define a pressure channel, such that when the channel is pressurized, the main body everts, and inverted material of the main body everts and passes out of a tip at a distal end of the main body. A reeling mechanism is controlled by a reeling motor, the reeling mechanism being within the tube and being configured to actively feed the inverted material to provide or assist eversion and to actively retract extended material of the main body back. Control and communications electronics control the reeling motor. T reeling mechanism can include a steering mechanism with a bending axis controlled by a steering motor. By actively supplying eversion or inversion forces in the robot body, the soft vine robot can grow with reduced pressure compared to base reeled robots.

摘要： This invention concerns a contractile device. The device includes a body, which has a wall including a tessellation of elements. The body is deformable through pressurisation of fluid within the body between a first, extended state and a second, contracted state in which the axial length of the body is reduced and the internal volume increased compared to the first, normal state. The tessellation of elements includes a series of protruding and intruding formations which are arranged such that the body remains substantially cylindrical through its deformation between its normal and deformed states. The protruding and intruding formations of the tessellation of elements may be in the form of protruding and intruding pyramids.

摘要： Hydraulically amplified self-healing electrostatic (HASEL) transducers having a composite, multi-layered structure. Specifically, a layered composite structure is contemplated such that different ones of the layers are selected for electrical properties and physical properties, respectively. Specifically, combinations of fluid dielectric layers, solid dielectric layers, electrodes, and outer layers may be used. The fluid and solid dielectric layers may be selected for favorable electrical properties and the outer layers may be selected for beneficial physical properties. An example of a composite structure includes individually actuatable fluid dielectric volumes that may have different actuation modalities. Further still, transducers may be provided with gaseous dielectric, fluid dielectric, or a combination thereof.

摘要： A method of performing wireless actuation by inductive heating of magnetic particles. The method provides a bladder having an inner surface and an outer surface, the inner surface forming an interior area, the bladder configured to expand or retract so as to change an area of the interior area, (ii) a plurality of magnetic particles suspended in a fluid medium and disposed within the interior area, and (iii) a sleeve disposed on the outer surface of the bladder. The method excites the plurality of magnetic particles by application of an alternating magnetic field to which the particles reaction. The method causes, by the excited magnetic particles, a phase transition to the fluid medium within the interior area which causes the bladder to expand, such that the sleeve confining the bladder generates actuation from the expansion or retraction of the bladder.

摘要： A textile actuator worn by a user comprises a textile envelope that defines a chamber made fluid-impermeable by a fluid-impermeable bladder contained in the textile envelope and/or a fluid-impermeable structure incorporated into the textile envelope. The textile envelope has a pre-determined geometry that produces an equilibrium state at a non-180-angle displacement and that stops further displacement upon pressurization of the chamber and prevents over-extension the joint. A fluid is delivered into or out of the chamber to displace the textile envelope primarily by transitioning from an uninflated state to the pre-determined geometry due to displacement of the textile envelope rather than via stretching or contraction of the textile envelope. When actuated, the textile actuator (a) displaces a body segment of the user and/or (b) supports and holds the body segment of the user in place.

摘要： An artificial muscle system includes a collapsible skeleton, a flexible skin, and a muscle actuation mechanism. The collapsible skeleton is contained inside a volume defined, at least in part, by the flexible skin. The flexible skin and the collapsible skeleton are configured for the flexible skin to provide a pulling force on the collapsible skeleton when a pressure difference exists between the inside of the sealed volume and a surrounding environment to change at least one of the dimensions and thus geometry of the collapsible skeleton. The muscle actuation mechanism includes at least one of the following to deploy or contract the collapsible skeleton: (a) a fluid displacing, releasing, or capturing mechanism configured to increase or decrease fluid pressure inside the sealed volume; and (b) a heating or cooling element configured to change the temperature of fluid in the sealed volume.
