A micro-muscular breakthrough: Powerful new microscale torsional muscle/motor from vanadium dioxide

Researchers have demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length faster than the blink of an eye.
