Advanced Artificial Leg Allows Amputees to Feel Sensations in Their Foot

Austrian scientists have invented a revolutionary product in the world of prosthetics – an artificial leg with lifelike sensations. The one-of-a-kind man-made limb has sensors fitted to the sole, which are able to stimulate nerves at the base of the amputee’s stump.

“It feels like I have a foot again,” said Wolfang Rangger, the very first recipient of the sensory-enhanced prosthesis. “I no longer slip on ice and I can tell whether I walk on gravel, concrete, sand, or grass. I can even feel small stones.”

Venezuelan Man Builds His Own Prosthetic Arm

Angel Sanguino, an electronics technician from Caracas, Venezuela, who last year lost his left arm in a motorcycle accident, has recently been awarded a Prize for Science, Technology and Innovation, after he manged to build an ingenious robotic arm that allows him to perform a series of useful tasks.

33-year-old Angel Sanguino was riding his motorcycle when he was hit by a speeding car engaged in illegal street racing. He was taken to the emergency room, and doctors were forced to amputate his left arm from the shoulder. It was a devastating blow for the talented electronics technician who worked for a prestigious computer part manufacturer, as he could no longer do his job with just one arm. The orthopedist told Angel he should accept his disability and move on with his life, but he had other plans. While in intensive care recovering from the surgery, severe internal organ damage and fractured legs, Sanguino learned he was going to become a father soon, and that gave him the strength to fight for his life and make sure he was able to provide for his family. Three months after his accident, the young Venezuelan used his experience as a cartoonist to design a prosthetic arm that would allow him to repair electronic components just like before.

Japanese Prosthetic Expert Makes Fake Fingers for Ex-Yakuza Members

Shintaro Hayashi, a prosthetics maker from Japan, is helping out former members of the Yakuza, or Japanese mob, by creating fake fingers they lost during their life of crime, so they can get normal jobs easier.

The Yakuza organized crime syndicates are renowned for their strict codes of conduct and organized nature. When a member causes serious offenses, he is required to perform a ritual known as “yubitsume”, which implies cutting off his own fingers as a form of atonement. Usually, the left pinkie is the first one to go, but repeated mistakes can cause a sloppy Yakuza to lose several digits. It becomes a stigma that signifies current or former membership in the Japanese mafia, and those who manage to leave their troubled past behind and become reformed citizens have a hard time finding jobs because of it. Most Yakuza try to conceal their missing fingers in public by keeping a fist, but there comes a time when they can’t hide their defects anymore, and that’s where prosthetics maker Shintaro Hayashi comes in. For the last 10 years, he has been creating fake fingers to mask Yakuza amputations. Read More »
