Researchers have developed improved forms of tiny magnetic
actuators thanks to new materials and a microscopic 3D printing technology.
Scientists have been conducting research on micrometre-sized
actuators which one day may make it possible to transport drugs or chemical
sensor molecules to specific locations throughout the human body. Researchers
at ETH Zurich have now taken the development of such micro-devices a crucial step
forward: a new production technology and new materials have made it possible to
manufacture tiny actuators in any form and optimise them for future
applications.
