Recent advances scientists suggest, that someday miniature robots can navigate in the human body, delivering medication to the patient or body engaged in clearing the arteries by cholesterol plaques. But the human body contains a completely different environment, therefore, these robots must be able to adapt to changes in the environment "on the fly". Researchers at the École Polytechnique Fédérale de Lausanne (EPFL) and the Swiss Federal Institute of Technology Zurich (ETH Zurich) developed micro-robots, which can change shape automatically according to the environment.
Microrobots consist of several layers of biocompatible hydrogel, folded like origami - construction, used to create many tiny robots, for use in the body. The hydrogel embedded tiny magnetic particles, so its fibers can be moved remotely, using an alternating electromagnetic field.
