Chinese scholars build liquid metal magnetic micro soft robot

News on October 22, according to reports from Science and Technology Daily, the public account of Harbin Institute of Technology Shenzhen Campus, etc., the team of Professor Ma Xing and Associate Professor Jin Dongdong of the School of Materials Science and Engineering of Harbin Institute of Technology (Shenzhen) recently constructed a liquid metal Magnetic miniature soft robot, related results have been published in the journal "Nature Communications".

According to reports, the robot is expected to enter narrow areas of the human body to perform diagnosis and treatment tasks, especially areas that are difficult to reach with conventional medical methods, and has huge application potential in the biomedical field.

Compared with rigid robots, this kind of robot has a higher degree of freedom of deformation and flexibility. It can change its shape and motion state according to changes in the external magnetic field, and can better absorb collisions when it enters the human body. Energy, thus effectively making up for the difference in mechanical properties between machines and humans, with higher safety.

In addition, this kind of magnetic micro soft robot can achieve a variety of large-scale controllable deformation and active and passive deformation, sorting, fusion, migration and other motion behaviors through the drive control of programmed external magnetic field. The team has now verified the feasibility of the robot's application in the gastric environment under endoscopy and X-ray imaging, providing strong support for the clinical application of liquid metal microsoft robots.

The above is the detailed content of Chinese scholars build liquid metal magnetic micro soft robot. For more information, please follow other related articles on the PHP Chinese website!
