The human skin, with all its frailties, turns out to be difficult to recreate, let alone improve on. The main challenge: It manages to be both self-healing and sensitive to the touch, enabling it to send vital information to the brain about temperature and pressure.

But chemists and engineers at Stanford say they are one step closer to developing an electronic skin that has both these properties, and they report this week in the journal Nature Nanotechnology that it could help lead to smarter prosthetics and more resilient, self-repairing electronics.

Their central task was to find a self-healing material (a … Read more

Several months ago, my colleague Tim Hornyak wrote about the BeBionic 3 myoelectric prosthetic hand, a landmark prosthesis that enables a spectacular range of Terminator-like precise gripping and hand maneuverability.

A video making the rounds this week stars 53-year-old Nigel Ackland -- a wearer of the device -- who shows us that we've come extraordinarily far in prosthetic research, perhaps shockingly so if you don't keep up with the subject. … Read more

This Sunday, amputee Zak Vawter will stand at the foot of Chicago's Willis Tower and focus his thoughts on climbing. If all goes according to plan, his bionic leg will listen to those thoughts and he'll ascend 103 flights without a hitch.

Vawter, who lost his right leg in a motorcycle accident in 2009, will be wearing a cutting-edge, thought-controlled prosthetic that's about to make a very public debut. He'll head up the 1,451-foot skyscraper (also known as Sears Tower) as part of SkyRise Chicago, an indoor stair-climbing fund-raising event for the Rehabilitation Institute of … Read more

It's still no match for the human hand, but RSL Steeper's BeBionic 3 looks way cooler.

The company is launching a more powerful, durable version of its prosthetic today at a gathering of the American Orthotic Prosthetic Association (AOPA) in Boston.

The BeBionic 3 has an aluminum chassis, improved electronics, a redesigned thumb, and new motors that increase the power grip strength from 16.8 pounds to 31.5 pounds, according to SteeperUSA.

In hook mode, when a weight is carried by all fingers, the hand can bear 99 pounds, up from 70.5 pounds. … Read more

Few would have mustered the optimism or the ingenuity.

But Sun Jifa didn't have the money to buy replacements. What else was he supposed to do but build his own?

Did Sun, 51, of Guanmashan, northern China, need new seats for his car or coffee tables for his living room? Not quite.

He needed new hands, after he'd blown off his own.… Read more

Do you have a cochlear implant? An intraocular lens in your eye? A prosethetic leg with microservos? You may not realize it, but you're standing on the front line of a new age of medical augmentation, one that's raising a host of complex questions.

Who owns the expensive implant that allows you to hear or see better or the sleek thin blades that let you sprint faster? How are upgrades to your device handled? What happens to you and your device if that company goes out of business? Do the answers change if the procedure is elective rather than life-saving?

No one has easy answers, or even much beyond informed speculation -- certainly not the doctors we spoke to for this article or the medical students who addressed medical augmentation at a Defcon 20 session last month in Las Vegas. But all agree on one thing: A new frontier of medical augmentation isn't just coming sooner than you think. It's already here, as society moves from medically necessary augmentation to elective procedures. Call it human hacking. … Read more

In the future when we'll all be wearing robotic exoskeletons, we'll laugh when we think back on the days when we were mere meatsacks. German automation firm Festo is helping us upgrade with the ExoHand, a glove controller that can give people a machine handshake.

Known for its elegantly engineered SmartBird robot seagull, Festo says its ExoHand can not only teleoperate a robot hand in a master-slave control relationship, it can reduce strain from repetitive tasks when using your own old-fashioned, flesh-and-blood hands. … Read more

SAN FRANCISCO--For people like Sarah Reinertsen, one of the many downsides of having a prosthetic leg is that there's never been a fashionable way to dress it up.

But for Reinertsen, a record-setting triathlete, and others including a growing number of combat veterans, a startup called Bespoke Innovations is forever changing the way they feel about themselves and how the world looks at them.

Bespoke was founded by industrial designer Scott Summit and orthopedist Kenneth Trauner. The company's initial products are what are known as fairings--3D printed prosthetic leg covers that are each one-of-a-kind and designed for and … Read more

What's an 8-foot-tall Lego man doing on the beaches of Siesta Key Village, Florida? We don't have the answer, but it's the third one that's washed ashore in the last three years--similar occurances were reported three years ago in Brighton, England, and Zandvoort, Holland; each bearing the same cryptic messaging: "NO REAL THAN YOU ARE."

Yahoo News did the dirty work and inquired about the phenomenon to Lego's assistant brand relations manager, who vehemently denied, on record, any affiliation with the stunt, eliminating the possibility of it being a viral stunt. Who knows, maybe it was printed on a 3D imaging device by the folks at MakerBot!… Read more
