  • Patent number: 10843336
    Abstract: Reconfigurable soft robotic actuators with hard components are described. Magnetic attraction is used to couple flexible molded bodies capable of actuation upon pressurization with other flexible molded bodies and/or with hard components (e.g., frames and connectors) to form a seal for fluidic communication and cooperative actuation. Pneumatic de-coupling chambers built into the hard components to de-couple the hard components from the magnetically-coupled soft molded bodies are described. The use of magnetic self-alignment coupling and pneumatic de-coupling allows for the remote assembly and disassembly of complex structures involving hard and soft components. The magnetic coupling allows for rapid, reversible reconfiguration of hybrid soft-hard robots for repair, testing new designs, and carrying out new tasks.

  • Publication number: 20200178388
    Abstract: Disclosed are a fiber composite laminate including a self-assembled conductive paste and a method of manufacturing the same. The fiber composite laminate includes a fiber-based circuit unit including a fiber substrate and a circuit electrode positioned on the fiber substrate, a composite binder unit positioned on the fiber-based circuit unit, and a connection unit including a connection electrode positioned on the composite binder unit and a flexible substrate positioned on the composite binder unit and the connection electrode. The fiber composite laminate can thus be applied to wearable devices having increased conductivity and durability of joints thereof, a minimized foreign-body sensation, and an improved wearing sensation. Moreover, productivity can be increased owing to a simple manufacturing process, and mass production becomes possible.

  • Publication number: 20170001419
    Abstract: Multi-stage composite materials, their preparation, and their uses are described. A composite includes a first layer of a first material contributing to mechanical strength of the composite having a first length, and a second layer of a second material contributing to the mechanical strength of the composite having a second length, wherein the second length is greater than the first length, wherein the second length of the second layer is affixed to the first length of the first layer at both ends of the first and second lengths so that the second layer is spaced apart from the first layer.

  • Patent number: 9437922
    Abstract: A method of manufacturing a fluidic structure is disclosed. A cavity that defines a shape of an element of the fluidic structure within a material is formed. The cavity is filled with liquid metal. The cavity is sealed. The fluidic structure behaves as an antenna. A fluidic antenna includes a material that defines a shape of the fluidic antenna by a cavity filled with liquid metal formed within the material, where the material further defines at least one mechanical property of the fluidic antenna.

  • Publication number: 20160221302
    Abstract: Composite materials that are configurable, their preparation, and their uses are described. A composite article includes a plurality of sheets positioned to interleave and partially overlap with each other and held together by interactions between the plurality of sheets and a compressive force across the plurality of sheets, wherein each of the plurality of sheets is infused with an elastomer and forms at least one smooth surface, wherein each of the plurality of sheets is in close contact with adjacent ones of the plurality of sheets, wherein an overlapping area of the plurality of sheets provides resistance to a shear force applied to the composite article.
