Researchers in Australia are working on a “micromotor” that’s only 250 micrometers wide, which is about 2.5 times the width of a human hair. They hope to mount sensors and cameras on the tiny flagellating device to assist in delicate and minimally-invasive surgical procedures. Neato.

"Serious damage during minimally invasive surgery is however not always avoidable and surgeons are often limited by the width of a catheter tube for example, which in serious cases, can fatally puncture narrow arteries," Professor Friend said.
