Enter the DEKA limb, the first FDA-approved robotic arm that’s powered by the wearer’s mind. Electrodes attached to the arm near the prosthesis detect muscle contraction, and those signals are then interpreted into specific movements by a computer, the FDA announced on Friday.
"The device is modular so that it can be fitted to people who’ve suffered any degree of limb loss, from an entire arm to a hand," Bloomberg Businessweek reported. ”Six ‘grip patterns’ allow wearers to drink a cup of water, hold a cordless drill or pick up a credit card or a grape, among other functions.”

These were conjuring tricks, sure—mere public spectacles, so to speak—but successfully achieving them required sophisticated understandings of basic physical factors such as light, shadow, and acoustics, making an audience see—and, most importantly, believe in—the illusion.
