  • Patent number: 11197726
    Abstract: Elastomer-based soft-robotic micro-tentacles capable of winding around and holding microscale objects and methods of fabricating same are provided. To realize the thin, highly deformable microtubes, a fabrication technique based on in situ thermal solidification of PDMS dip-coated around a cylindrical template and direct peeling of the cured structure is presented. This process is capable to asymmetrize the microtube's cross-sectional shape and enable the microtube to bend up to a single turn. To amplify the bending into a life-like, multi-turn spiraling motion, a semi-analytical model to shape-engineer the microtube and turn it into a micro-tentacle was produced. As a result, a hump is added to the microtube to enable the multi-turn spiraling motion.

  • Patent number: 11186025
    Abstract: A method and a device for producing fibre-reinforced plastic mouldings, using coated fibre strands. For the coating of the fibre strands, an air flow of ionised air is produced and guided through a Venturi nozzle. Powder from a storage container is taken by means of a screw conveyor and supplied to the Venturi nozzle, a flow of a powder-air mixture being present or forming behind the Venturi nozzle in the direction of flow. This stream is introduced into a chamber and fibre strands that are earthed or ionised unlike the powder are passed through the chamber and through the powder-air mixture flowing through the chamber, powder particles being deposited on the fibre strands. The fibre strands guided out of the chamber therefore have a coating, and the fibre strands coated in this way are supplied to a plasticising device of an injection moulding machine or an extrusion machine.
