Moto Knee performance prosthetic leg packs a Fox shock

By - June 11, 2014 6 Pictures
You probably wouldn't try using the same motorbike for both racing over rough trails and commuting on smooth roads, so ... why use the same prosthetic leg? That's the thinking behind the Moto Knee, a prosthesis that's designed for activities such as skiing, horseback riding, cycling and motocross. In order to withstand the impacts that come with such activities, it even incorporates a Fox DHX Air mountain bike shock absorber. Read More

New DARPA program to develop prosthetics with lifelike sensory feedback

By - April 25, 2014 1 Picture
Many modern prosthetic limbs are so intricate that they seem like something from the sci-fi cyborg realm. Unfortunately, to the wearer these marvels still feel like lumps of dead metal and plastic. DARPA's recently announced Hand Proprioception and Touch Interfaces (HAPTIX) program aims to change this. Using implantable sensors linked wirelessly to external modules, the goal is to provide lifelike prosthetic limbs with such a high degree of sensory feedback that they bring a sense of being part of the the wearer’s body, not something just strapped on.

Computer-controlled artificial leg offers a more natural gait

By - October 16, 2013 2 Pictures
Although computer-controlled artificial legs have been around for a few years now, they generally still feature an ankle joint that only allows the foot to tilt along a toe-up/toe-down axis. That's fine for walking in a straight line, but what happens when users want to turn a corner, or walk over uneven terrain? Well, in some cases, they end up falling down. That's why researchers at Michigan Technological University are now developing a microprocessor-controlled leg with an ankle that also lets the foot roll from side to side. Read More

DARPA uses nerve/muscle interfaces to give amputees feedback and improve control

By - June 2, 2013 2 Pictures
Artificial limbs have come a long way in recent years with the development of prostheses that can be controlled directly by the patient’s nerves. The problem is, links between living nerves and the prostheses break down over time, which makes permanent attachment and practical control difficult. To understand why this happens and to help give patients more control over their prostheses, DARPA has instituted a number of programs aimed at improving neural interfaces and allowing amputees to have better control of advanced prostheses in the near term.

Touch Bionics introduces app-controlled prosthetic hand

By - April 19, 2013 13 Pictures
Whichever marketing genius came up with the Apple catchphrase, "There's an app for that," has a lot to answer for – or brag about. It's heard so often these days that it’s become a cliché. Touch Bionic’s i-limb ultra revolution robotic artificial hand gives yet another reason to repeat the phrase. It’s linked to a smartphone app, which allows for greater control of the hand, including the ability to program it to suit the wearer’s personal needs. Read More

Argus II becomes first "bionic eye" to gain approval for sale in U.S.

By - February 18, 2013 4 Pictures
While the word prosthesis usually evokes images of artificial legs, arms, and these days even sophisticated thought-controlled hands, an entirely new class of replacement body part has now become a reality – the bionic eye. One of the pioneers in this field is California-based Second Sight and the company has now announced that its Argus II System has received U.S. market approval from the Food and Drug Administration (FDA).

Researchers transmit braille directly to the retina of blind test subject

By - November 23, 2012 1 Picture
Second Sight’s Argus II Retinal Prosthesis is definitely an interesting piece of technology, allowing a blind user to “see” objects, colors and movement in their environment. Ordinarily, this is done with the help of a video-camera-equipped pair of glasses worn by the user. In a recent experiment, however, researchers bypassed the camera, transmitting visual braille patterns directly to a blind test subject’s retina. Read More

Man to climb Chicago's Willis Tower using thought-controlled bionic leg

By - November 2, 2012 9 Pictures
Despite losing most of his right leg in a motorcycle accident, Zac Vawter (31) intends to climb all 103 flights of stairs at Chicago's Willis Tower this Sunday. He's been helping researchers at the Rehabilitation Institute of Chicago (RIC) test a cutting-edge bionic leg that is controlled by his own nerve impulses. He can walk, kick a ball, and climb stairs by simply thinking of what he wants his leg to do. Read More

AMP-Foot 2.0 prosthesis mimics human ankle's spring

By - October 31, 2012 2 Pictures
The majority of protheses available today that replace the lower leg, ankle, and foot are passive devices that store energy in an elastic element (similar to a coiled spring) at the beginning of a step and release during push-off to give you some added boost. While this type of prosthetic is energy efficient, it doesn't replicate the full power we get from our muscles. In order to provide that kind of energy an actuator is required, and these are often heavy and bulky. Researchers at Belgium's Vrije Universiteit Brussel have streamlined the technology in a device they call the AMP-Foot (Ankle Mimicking Prosthetic Foot). Read More
