Bionic muscles that are stronger, faster, and more efficient
by Rahul Rao

Artificial muscles, once a tangle of elaborate servomotors, and hydraulic and pneumatic actuators, is now a thing of shape-memory alloys and hair-thin carbon nanotube (CNT) fibers. Bionics are, in brief, getting smaller—though perhaps not simpler. Electrochemical CNT muscles are also energy efficient, and they provide larger muscle strokes as well. Recently, a group of researchers from the U.S., Australia, South Korea […]
