Editor's take: Researchers from the City University of Hong Kong have developed a special type of spray that can give objects magnetic properties. Through the use of an external magnetic field, the ...

Millirobots that can adapt to unstructured environments, operate in confined spaces, and interact with a diverse range of objects would be desirable for exploration and biomedical applications.

Physicists have developed an inexpensive, highly accurate magnetic field sensor for scientific and possibly consumer uses based on a “spintronic” organic thin-film semiconductor that basically is ...

(Nanowerk News) An easy way to make millirobots by coating objects with a glue-like magnetic spray was developed in a joint research led by a scientist from City University of Hong Kong (CityU).

An easy way to make millirobots by coating objects with a glue-like magnetic spray has been developed. Driven by the magnetic field, the coated objects can crawl, walk, or roll on different surfaces.
