Comments (22) Add to My Stories Share A prosthetic technology company has unveiled an ultra-realistic range of limbs with features such as freckles, hairs and even tattoos.
Scottish company Touch Bionics have been hand-crafting upper limb prostheses for years but have recently introduced a new photographic system that is designed to make passive prostheses look as real as possible.

The products, which come in parts of fingers, whole fingers, hands or arms, are known as passive prostheses - although light joints can be built in so they can be manually bent into different shapes.
Made from high definition silicone, they are part of the 'Living Skin' range and are designed with the help of a patent-pending imaging system called 'Living Image'.

Living Image has been under development for a couple of years and was revealed on Tuesday at Las Vegas at the American Orthotic & Prosthetic Association National Assembly.
If a patient needs a single prosthetic such as a hand or finger, experts use the system to scan the skin tone, features and shape of their remaining limb.
The system, which simulates natural light for the best colour match, sends the resulting image via the internet to the production facility in Scotland. The resulting prosthetic is hand-painted to exactly match skin tone and appearance.

Touch Bionics spokesman Danny Sullivan, told Mail Online: 'We've tested the system on 100 patients and it has been very successful.
'Clients have been very satisfied, especially with the colour of the 'skin.' The aim is to create a prosthetic that is as close a match as possible.'

The scanning process removes the need for time-consuming and error-prone matching practices and results in a highly realistic prosthetic in a shorter amount of time.
'It used to take five weeks to create a finger and seven weeks to create a hand,' Mr Sullivan said.
'But the imaging system has shortened this process by two to three weeks. It's also more reliable and makes far better use of clinical time.'

There are several systems at Touch Bionic centres in the U.S and one in use in the UK at the headquarters in Livingston in Scotland. There are tentative plans to either sell or rent systems to other prosthetic centres.
'We want to bring living skin to as wide a population as possible,' Mr Sullivan said.

The company also unveiled i-limb ultra, an upgraded version of its flagship prosthetic hand solution, which they say is the most versatile prosthetic hand available.

It has multiple functions including pushing, pulling, stabilising, supporting, light grasping and typing. It is the only prosthetic that can gradually increase the strength of its grip on an object.

Mr Sullivan said living image could be used to create coverings for their latest products.

Meet Rex: the $1m bionic man with working heart, set of lungs and human face

Most human body parts can be replaced, say scientists, and here’s the evidence
Kevin Rawlinson Author Biography , Tom Goulding

Tuesday 05 February 2013



When Luke Skywalker received a perfect bionic replacement for the hand that was cut off in Star Wars Episode V, the idea of replicating human organs and body parts seemed far-fetched.

Thirty years later, the idea is no longer just science fiction. Scientists, among them the creators of “Rex” – the world’s most complete bionic man, unveiled in London this week – believe they can now replicate about two-thirds of the human body.

“We were surprised how many of the parts of the body can be replaced,” said Rich Walker, managing director of the robotics team Shadow, who built Rex. “There are some vital organs missing, like the stomach, but 60 to 70 per cent of a human has effectively been rebuilt.” This is heralded, then, as the dawn of the age of bionic man – although specialists caution that we are still feeling our way.

Social psychologist Bertolt Meyer, who also worked on Rex, has an interesting perspective: he was born without his left hand and has a prosthesis. “I have looked for new bionic technologies out of personal interest for a long time and I think that until five or six years ago nothing much was happening,” he said. “Suddenly we are at a point where we can build a body that is great and beautiful in its own special way.”

Not everyone in the field believes the recent progress, impressive as it is, places us on the road to complete replication of human limbs, organs and tissue. “We have motors which can lift things but, if you want to mimic the dexterity of a hand, we are not there yet,” said Professor Steven Hsiao of the John Hopkins University in Baltimore.

“What we are beginning to achieve is building prostheses which look like human body parts, but we are a long way away from making ones which relay sensory information the way the human body does.”

Professor Hsiao drew the comparison between Star Wars and real life, saying: “The goal is the scene in the film where Luke Skywalker gets his new hand tested and is able to feel pain: we are not there. In 10 years, we will be able to build a robot which has the dexterity to pick up a pen and write with it, but it will not be able to send back sensory information.”

Rex, billed as the pinnacle of robotics achievement to date, will meet his public from tomorrow at the Science Museum in London. Dubbed the Million-Dollar Man (that’s how much he cost to make), he consists of a prosthetic face, hips, knees, feet and hands, all of which are commercially available. Other off-the-shelf items include an artificial retina, cochlea and heart.

Rex’s other internal organs, among them a pancreas, a set of artificial lungs and bladder, are still in development. Some of the technology cannot work without human input; bionic hands, for example, need muscles and signals from the brain to function. Other parts, such as the heart and pancreas, are designed to work on their own.

Other body parts remain out of the reach of scientists. Mr Walker says: “The only artificial stomach we have seen is very large and generates electricity, so you couldn’t use it to replace a human stomach, but I am sure there are people in the regenerative medicine community working on that.”

And replication of the human brain, the most complex structure known to man, was not even on the radar, Mr Walker said. “This is a showcase for prosthetic parts, it shows exactly where we’ve got to in being able to replace parts of a human.”

Bertolt Meyer adds: “I’d say it’s highly unlikely that, in our lifetimes or in that of our grandchildren, we will see a fully articulate human body with an artificial intelligence.”

Mr Meyer said there would be ethical issues surrounding prostheses if they began to outperform human body parts. “Should I be allowed to cut off my real hand and replace it with something, does that gives me an unfair advantage over people who cannot afford this? I’m not saying that is going to happen but these are questions that should be on the table before that technology becomes available.”
