Electromagnetic engines can’t be reduced to just any size. It takes clever engineering tricks to generate active movement in miniature format. Researchers in Bochum are constantly coming up with new technologies.

Over the years, a great many technical components have been shrunk in size. But miniaturization reaches its limits when tiny systems are supposed to move actively, because conventional electromagnetic motors become inefficient when reduced to miniature format. Researchers from the Chair of Microsystems Technology at Ruhr University Bochum, Germany, have therefore come up with clever tricks to set them in motion. Their systems are driven by electrostatic force. ...
