Recently, researchers at the Massachusetts Institute of Technology have developed a 3D-printed small software "robot" that can be manipulated by a magnetic field and is expected to be used in the field of biomedicine. According to a study published in the latest issue of the journal Nature, this "robot" is actually a 3D printed structure resembling a snowflake, which stretches completely to a maximum diameter of about 4 cm. Under the manipulation of the magnetic field, it can crawl, roll, jump, quickly shrink to catch the rolled ball, but also wrap the tablet to move on the table. MIT Professor Zhao Xuanhe, a professor of mechanical engineering at the Massachusetts Institute of Technology, used 3D printing inks doped with magnetic particles and installed electromagnets on the nozzles of 3D printers to control the direction of magnetic particles during the printing process, creating this kind of magnetic field that can be manipulated on the outside. Immediately under the fine deformation of the structure. According to reports, this “robot†controlled by magnetic fields does not require high voltage like some electrically-driven robots, but it is deformed more quickly than software robots made of materials such as hydrogels. The research team said that using this technology can also produce "robots" with different shapes and functions, such as the ring structure embedded circuit and red and green LED lights. Under the effect of an external magnetic field, the ring can be deformed to light the red light or Green light. Zhao Xuanhe said that this invention is expected to be widely used in the biomedical field. For example, a small “robot†can be placed near a blood vessel to control blood flow, or it can be used to guide the necessary equipment into the gastrointestinal tract, where it can take pictures and obtain tissue samples.
