An Israeli professor has developed a tactile contact lens that translates images recorded on camera into tactile sensations on the cornea to allow the blind to "see" objects.


Professor Zeev Zalevsky, head of "Electro-Optics" in the faculty of engineering at Bar Ilan University has built a prototype that will physically press images onto the surface of the eye in order to help the brain understand through tactile feedback what the person is looking at.


The system takes data from a mounted camera or mobile phone and transmits the encoded image via the contact lens to the wearer's cornea. The tactile sensation can then be interpreted by the wearer's brain so that they can understand what they are looking at. Zalevsky describes the technique as much like learning to read Braille.

Zalevsky hasn't been able to test the contact lens on humans yet, because he hasn't yet received approval to go ahead with the clinical trial, but he has tested an alternative system that uses air pressure instead of direct stimulation on the cornea. This alternative system involved a pair of glasses which had a matrix of small air tubes directed towards the cornea. These tubes were injected with air in such a way that they formed different shapes, creating pressure on the cornea. The people trying the system were able to identify the shapes (admittedly only ten clearly defined icons) with 90 percent accuracy after a few minutes of practice.

"It was much simpler to get the approval for doing the pressure tests on the cornea because [blowing air onto the cornea] is already part of a conventional medical procedure to test for glaucoma," Zalevsky told Wired.co.uk. "For electrical stimulation of the eye you need more complicated regulatory approval, which will take some time."


The contact lens will have electrodes embedded into it which will act like small antennas for electromagnetic waves which will be transferred wirelessly from another device. The camera will capture the image, which will then be processed, compressed and encoded before being transmitted to the contact lens to generate tactile stimulation. Zalevsky suggests that this could be done at around ten frames per second.

The technique is a non-invasive, higher-resolution alternative to artificial retinas that use electrodes to directly stimulate the optic nerves. It will also work for those people who were born blind and so have not developed a visual cortex. In this case, stimulating the retina will not create images in the brain.

Zalevsky's technique is not without its resolution challenges however. Although the cornea is jam packed with nerve endings, it has a problem with two-point discrimination. This is the smallest spatial difference that a person can identify between two sources of stimulation, in this case on the cornea. Zalevsky's team discovered that the two-point discrimination of the cornea from a tactile point of view is less than a millimetre. This means there is a limit to how many pixels can be stimulated on the cornea. Having said that, the cornea is pretty large compared to the macula, which is what those developing bionic retinas have to play with.

Zalevsky believes the system could also be used by people who already see well but want to access supplementary information, in a Google Glass sort of way.

For the time being the focus of Zalevsky's spin-out company, IC Touch, is to raise funding to develop the prototype further and carry out the full clinical trial. "Then we can mature it into a product that will eventually benefit blind people around the world," he told us.

The First To Ever Receive World's Most Advanced Prosthetic Ticker, Built By Carmat
The world’s most advanced artificial heart was implanted for the first time in a human patient this week in France. According to the French company that designed and developed this technology, Carmat, the procedure has gone according to plan so far, with the prosthesis providing appropriate blood flow while the patient is awake and talking in the intensive care unit.

“We are delighted with this first implant, although it is premature to draw conclusions given that a single implant has been performed and that we are in the early postoperative phase,” Marcello Conviti, CEO of Carmat, commented in a statement.

Last September, Carmat gained French approval to implant their artificial heart device in four patients who were suffering from terminal heart failure and had a limited amount of time to live, Reuters reported. At the time, the company had already gotten the go-ahead in Belgium, Poland, Slovenia, and Saudi Arabia.

The heart prosthesis has four cavities that are arranged similarly to the chambers of a human heart with two on the right and two on the left. Each of these four cavities are separated into two spaces by a flexible biomembrane made of bovine tissue; one space is for blood and the other is for a so-called actioning fluid. Two motor pumps alternately suck and inject the actioning fluid into the cavities to mimic heart muscle contractions, inducing the blood to flow in a timed manner and in the correct direction. Sensors are built into the system so that blood flow can adjust to a patient’s physical demands.


The technical aspects of the Carmat device were developed by the European Areonautic Defense and Space Company, which is the parent company of the aircraft manufacturer, Airbus. The inventor of the world’s most ubiquitous replacement heart valve, Professor Alain Carpentier, provided the medical know-how in developing the gadget.



The implant weighs approximately 2 lbs. and costs as much as a top-of-the-line Aston Martin sports car; between $190,000 and $250,000, according to Reuters. The device will be more often used on men because they suffer from heart failure more than women and because the innovative implant weighs almost three times that of a healthy heart. Yet Conviti conveyed to Reuters about the possibility of producing smaller versions that would be more suitable for people who wouldn't be able to handle the dimensions of the current implant, which is relevant not only to women but also to countries that have smaller average body sizes.

Carmat describes artificial hearts as “the only credible response for all cases of end-stage heart failure,” and identified the public health crisis stemming from heart disease being the world’s leading cause of death. According to a World Health Organization (WHO) estimate, ischemic heart disease killed 7 million people in 2011, which is 48 percent of the total number of deaths caused by the world's top ten leading klllers.

The company plans to conduct clinical trials that are split into two successive phases. The first stage involves testing the safety of the prosthesis on four end-stage patients with success hinging on a patient surviving for 30 days or eventually getting an actual heart transplant. The subsequent phase will involve around 20 patients who will undergo a more detailed assessment. In addition to survival, the patients’ level of functional improvement, organ rehabilitation, quality of life, and comfort will be scrutinized. After six months of collecting data — and nothing goes disastrously wrong — the company will go through another regulatory phase before it can begin marketing its bioprosthetic heart. Conviti told Reuters in November that Carmat hoped to finish human trials of the heart by the end of next year and to obtain approval to market them in the EU by early 2015.

The idea is that you can load your own materials into the machine and then let it “print” the food, that large manufacturers can make instant meals in the printer capsules or perhaps that small suppliers, artisanal style stuff, can make those capsules.



But the mystery here is really what is the problem that the Foodini is trying to solve? It doesn’t cook anything, it doesn’t time anything, spice it, flavour it, all of the things that determine how good or bad food tastes. All it can in fact do is lay it out for you.



The quality of the food will therefore be exactly and only the quality of the ingredients, how they have been combined and how they are cooked. Which are all things that are determined not by this piece of gadgetry at all. They’re determined by whoever it is that has put together the mixtures that are then printed. Which could be, as now, us, large manufacturers or getting in a takeaway from the local artisanal place around the corner.

Meet the new Apple’s next-generation iPhone 6 will finally match up to its key Android rivals and pack a 5-inch, Full HD 1080p display. That’s according to new rumours emerging from Japan, published in Mac Fan magazine.



The move to a larger screen would not be a huge surprise. Apple is said to have been testing larger, phablet-style phones for months, with a slew of stories of 6-inch devices emanating from supply-chain sources throughout the summer.

This new piece of tittle tattle, though, says a 5-inch number is nailed-on. While Mac Fan’s sources' credentials as sources of juicy info remain unclear, it's undoubtedly fair to say that a device of that size wouldn’t be seen as too large by most consumers.

The magazine also claims the iPhone 6 will launch in September 2014. That seems almost a given, what with the iPhone 5s and iPhone 5 arriving in the same timeframe in the past two years.

Expect to hear plenty more gossip about Apple’s next iPhone as 2014 looms into view.
