Researchers have created a prosthetic hand that offers its users the ability to feel where it is and how the fingers are positioned — a sense known as proprioception. The headline may be in jest, but the advance is real and may help amputees more effectively and naturally use their prostheses.
Prosthetic limbs have come a long way from the heavy, solid hands and legs of yesteryear, but it’s still difficult to pack a range of motion into them without complex or bulky machinery. But new research out of Cornell uses a cleverly designed 3D-printed mechanism to achieve speed and strength with simple construction — and it costs a lot less, too.
A pair of Canadian students making a simple, inexpensive prosthetic arm have taken home the grand prize at Microsoft’s Imagine Cup, a global startup competition the company holds yearly. SmartArm will receive $85,000, a mentoring session with CEO Satya Nadella, and some other Microsoft goodies. But they were far from the only worthy team from the dozens that came to Redmond to compete.
Prosthetic limbs are getting better and more personalized, but useful as they are, they’re still a far cry from the real thing. This new prosthetic ankle is a little closer than others, though: it moves on its own, adapting to its user’s gait and the surface on which it lands.
The science of prosthetics has been advancing by leaps and bounds over the last few years, and research into soft robotics has been especially complementary. The same techniques that go into making a robot arm that flexes and turns like a real one can go into making more complex, subtle organs — like the heart, as Swiss researchers have demonstrated.
