Research Status and Application Prospects of Magnetically Driven Micro- and Nanorobots

Micro- and nanorobots can effectively convert different energies into kinetic energy, and have been widely concerned by people for a long time. In recent years, magnetically driven micro- and nanorobots have become a research hotspot due to their excellent controllability and motion performance in complex environments. Micro- and nanorobots have the characteristics of wireless magnetically drive and control, and can adapt well to small and enclosed environments in vitro and in vivo. They have shown great potential in various fields such as biomedical, electronic, and environmental applications. This article first reviews the research progress of magnetically driven micro- and nanorobots both domestically and internationally in recent years, summarizes the exterior structure design, manufacturing methods, magnetic drive system selection and motion control methods of magnetically driven micro- and nanorobots, and then introduces the application research of magnetically driven micro- and nanorobots in the biomedical field. Finally, the problems and prospects of magnetically driven micro/nano robots are pointed out.
