A Micro-Muscular Break Through [Innovation]
posted December 23 2013 13:23.36 by spic0m




Berkeley Lab Researchers Make a Powerful New Microscale Torsional Muscle/Motor from Vanadium Dioxide.

"We've created a micro-bimorph dual coil that functions as a powerful torsional muscle, driven thermally or electro-thermally by the phase transition of vanadium dioxide," says the leader of this work, Junqiao Wu, a physicist who holds joint appointments with Berkeley Lab's Materials Sciences Division and the University of California-Berkeley's Department of Materials Science and Engineering. "Using a simple design and inorganic materials, we achieve superior performance in power density and speed over the motors and actuators now used in integrated micro-systems."
