  • Publication number: 20240299715
    Abstract: The disclosure belongs to the technical field of capsule robotics, and in particular, relates to a magnetically driven capsule robot with controllable drug administration and sampling functions and a fabrication method thereof. A magnetically driven capsule robot provided by the disclosure includes a robot body and a magnetic field-driven control module. The robot body includes a capsule shell, two ends of the capsule shell are provided with hollow air chambers, and a carrier chamber is disposed between the hollow air chambers disposed on the two ends. A substance transfer channel, a magnetic lock disposed around the substance transfer channel, and a magnetic soft switch valve matched with the magnetic lock are disposed on a side wall of the carrier chamber. The soft valve automatically closes due to the magnetic attraction force between the lock and valve, and can be flexibly opened under a magnetic torque acting on the valve.

  • Patent number: 11705263
    Abstract: The present invention belongs to the technical field of magnetically controlled soft-bodied robots, and more specifically, relates to a controllable and reconfigurable magnetization system and method for a magnetic soft-bodied robot. The system comprises a pulse power supply module, magnetizing coil units axisymmetrically arranged up and down, and a magnetic soft-bodied robot placed between the upper and lower magnetizing units. By means of changing the relative current flow direction of the upper and lower magnetizing coil modules, radial and vertical magnetic fields can be generated between the magnetizing coils arranged oppositely without any mechanical movement, so that the internal magnetization direction of the magnetic soft-bodied robot can be configured simply and flexibly.

  • Patent number: 11493581
    Abstract: Disclosed are a pulse magnet device based on magnetic flux compression, and a high-flux measurement method. The device includes a diamagnetic block, reinforcing plates, screw rods and a magnet coil. The diamagnetic block and the magnet coil are concentrically arranged in the axial direction; the reinforcing plates are arranged at ends of the magnet coil and the diamagnetic block and are connected by means of the screw rods. The diamagnetic block is used for inducing the induction current opposite the coil current during the discharge of the magnet coil, and for compressing the magnetic field to the area between the diamagnetic block and the magnet coil. The intensity and uniformity of the magnetic field around the magnet coil are improved by means of increasing the magnetic flux density.

  • Patent number: 11471926
    Abstract: Electromagnetic manufacturing method and forming device of mesoscale plate are provided. The manufacturing method includes: oppositely and parallelly disposing a first workpiece to be formed on top of a mold, side-press restraining two ends of the first workpiece, and disposing a deceleration block on two sides of the mold; controlling the first workpiece to tend toward the mold and to be deformed under the drive of uniform electromagnetic force; and colliding a middle area of the first workpiece firstly with the mold under the drive of uniform electromagnetic force, and driving the speed of the middle area of the first workpiece to decelerate to zero. When an area close to the two ends collides with the deceleration block and until the speed of all areas of first workpiece decelerates to zero, forming is completed. Shaping is tending further toward the mold through electromagnetic force until completely fitted to the mold.
