The magnetic hammer mechanism may be useful for small surgical interventions in the future. Researchers at the University of Houston have developed a magnetic hammer that sits inside a tiny robot which can move through mammalian brains. Although this sounds like the plot of a science fiction movie, the invention could have important implications for […]
With just the wave of a magnet, MIT researchers can control soft 3D printed structures and make them complete a range of movements, such as crawling, rolling up or jumping. The engineers believe this technique could be used for "promising applications" in biomedicine.
