For a man who left school with no qualifications, Chris Toumazou has done remarkably nicely in the intervening many years. He is at the moment chief scientist of Imperial School London’s Institute of Biomedical Engineering and holds much more than 50 patents for health care diagnostic instruments and other products. For very good measure, he will learn on 17 June if he has won this year’s prestigious European Inventor Award for his creation of a lab-on-a-chip technologies, a program that can test for genetic illness and drug intolerances in sufferers in less than 30 minutes.
It is a startling set of achievements, however Toumazou, who will be 53 following month, insists his breakthroughs have been based on the easiest approaches. “I set out to develop chips that used lower-energy technological innovation and that has allowed me to create gadgets that can do all their information crunching on web site.
“It is the extremely antithesis of large data, exactly where you gather every single bit of data that you can get hold of and send the whole lot to a processing centre, which will get clogged up in the approach. We must be looking, as considerably as feasible, at performing regional analyses ahead of transmitting outcomes. I am totally opposed to the concept of huge data.”
An example of this method is presented by his Sensium pads, says Toumazou. The size of a big plaster, these are caught, utilizing basic adhesives, on patients’ chests. They can then measure their heart prices, respiration, ECG signals and temperature. Crucially, these pads are inexpensive simply because of their low power demands.
“You use them for a few days and then throw them away,” he explains. “They value about £25. The US Food and Drug Administration has just authorized them and I envisage Sensium pads currently being used with hospital individuals who are recovering from operations. Rather of a ward sister going round checking every patient’s wellness in the standard manner, every will have a Sensium that will quickly increase the alarm if some thing goes wrong with a patient’s heart rate or temperature.”
The invention of products this kind of as these forms an extraordinary technological pedigree. But coming, as they do, from someone who had this kind of an inglorious commence to his academic job, they represent an extraordinary alter in conditions. The son of Greek Cypriot immigrants, Toumazou failed his eleven-plus and left college in Cheltenham at the age of 16. “I just did not get on at my school. It completely failed to inspire me,” he says.
A occupation in the family’s catering enterprise – “kebab eating places and fish and chip shops”, as he puts it – seemed inevitable. “It was anticipated of me but I felt I must do something various and as I was interested in electrical power I decided to study it at the local City and Guilds. I had a yr there finding out how to solder wires, which is ironic, as I can hardly correct a plug nowadays.”
Toumazou did effectively, particularly on the theoretical side of his electrical scientific studies. He took a two-year ordinary national diploma followed by a degree in engineering at Oxford Polytechnic, now Oxford Brookes University, and then a PhD. “I was informed I had written a excellent thesis, so I utilized to Imperial School to do a submit-doc and, to my disbelief, I was accepted.”
It was practically nothing to what was to come, even so. Two years later, he was produced a lecturer and then, 3 many years soon after that, Toumazou – unencumbered by a single A-level – became professor of electrical engineering, the youngest professor ever appointed at Imperial. Someplace along the road from Cheltenham, a man who after seemed destined for function in a kebab store shifted from reduced to the highest achievable gear and was now a main player at 1 of the world’s most distinguished scientific centres.
“I worked actually, truly difficult,” he says. “I wished to obtain. I wished to provide. I appreciated the innovative side and certainly it has been an fascinating journey. If absolutely nothing else, it has produced my mum and dad really pleased, specially when they met the Queen when she opened my Institute of Biomedical Engineering.”
When he began at Imperial in the late 80s, Toumazou’s main curiosity was in microchips. “But I was interested in analogue, not digital, electronics,” he adds. “Digital electronics is squashing signals into ones and zeros. But speech, sound and vision are all analogue signals, and in those days converting analogue to digital monopolised most of a gadget. I made a decision to locate a way to make all that analogue conversion so that it could run on extremely, extremely low power, thus permitting you to make very small telephone gadgets.”
The biological planet is analogue, of course, and Toumazou’s philosophy meant he could produce instruments that would interface between the living and the electronic. The initial outcome was his operate, a collaboration with other groups, on cochlear implants. Toumazou’s minimal-energy analogue chips made it achievable to produce an implantable device that would restore hearing to a youngster born with a significantly impaired cochlea, who would otherwise have suffered profound deafness. After that, he designed the Sensium pad and later his DNA chip technological innovation, goals to which Toumazou was driven with added intensity when it was discovered his son Marcus had a genetic issue that was slowly destroying his kidneys.
“Marcus had to go on a dialysis machine for three years soon after he misplaced his kidneys. Then he had a transplant but misplaced this kidney 6 many years later. Right now he is 22 and back on dialysis. I learned the tough way how desperately primitive is the technological innovation we have for monitoring the overall health of someone with a chronic sickness. Yet again, that influenced my function.”
To improve health monitoring, Toumazou decided to consider to place pieces of DNA in microchips and in carrying out so discovered he could make gadgets that would trigger signals when they came in speak to with a certain DNA sample. “I had discovered a way to create a chip that could recognise a genetic mutation in a DNA sample positioned on it. The device can tell you if you have a predisposition to a condition or no matter whether you can metabolise a health care drug or not. A GP can get a consequence from a patient in 15 to 20 minutes.”
To use the lab-on-a-chip technique, a doctor takes a sample of their patient’s saliva. DNA is extracted, particular gene sequences are amplified and, from these, an analysis can be displayed on a laptop in much less than half an hour. “You will be informed then and there just how your patient will react to a drug,” adds Toumazou. People individuals will not have to come to your surgery to modify their dosage depending on their reactions to the drug.
“You will know how they will react from the outcomes of the DNA chip check that you have just carried out. Or you could test if a individual has a mutation that is triggering a certain set of signs and symptoms. The essential point is that by using this sort of technologies we can get health care diagnoses that after took days or weeks in a number of minutes.”
It remains Toumazou’s most promising invention, though a stream of ideas continues to pour from him, like the creation of a assortment of genetically chosen cosmetics for women, which he is advertising and marketing later this yr with the former Duran Duran singer Nick Rhodes, underneath the title GeneU. “That is strictly company, of course,” he adds. “My major work is nevertheless centered on turning the silicon technologies into health-related devices for the 21st century.”
Luigi Cassar
Self-cleansing concrete
Air pollution has turn out to be 1 of the main environmental difficulties for industrialised nations. Cities devote hundreds of thousands on restoring buildings broken and discoloured by the fumes and millions a lot more on the public wellness concerns created by breathing in pollution day in, day out. With urban populations continuing to grow, the concern is only being exacerbated.
As a chemist, Luigi Cassar spent twenty years looking into the results of air pollution and its implications on buildings and wellness. But it was throughout the 1990s, when he was doing work for a cement company, that he ultimately developed a answer that keeps buildings grime-free of charge and cleans the air. By adding the organic mineral titanium oxide to concrete, Cassar and his group had been in a position to create a “photocatalytic” materials. When sunlight hits the titanium oxide, it binds electrons, enabling the formation of hydrogen peroxide on the concrete’s surface. This in turn interacts with the filth and other organic substances and turns them into nitrates, which are then basically washed away by rainwater.
It was as a side-effect to this self-cleaning home that Cassar very first noticed, while creating a church from his material in 1996, how the new concrete also decreased the air pollution all around the new creating – by up to 70% in some cases. This new top quality was speedily seized on and its effect on reducing a key contribution in the formation of smog, nitrogen oxide, was confirmed in the lab. The application of one,000 sq m of the cement is the equivalent of planting 80 trees.
Since then, the product has been incorporated into not only concrete, but also mortar, plaster and paint. Any wall covered in these materials is capable not to just keep clean but constantly purify the air. Cassar reckons that if just 15% of surfaces in a city had been coated, air pollution could be diminished by 50%. Josh Davis
Terese Alstin & Anna Haupt
Inflatable bike helmet
Even though Alstin and Haupt have been studying industrial layout at Sweden’s Lund University, a nationwide debate started as to whether or not it must be mandatory for grownups to put on cycle helmets. In response, the pair decided to emphasis their thesis on seeing if they could come up with a helmet that people really desired to dress in, mandatory or not.
With only five%-twenty% of cyclists in Europe sporting a helmet, and cycling getting to be ever much more well-known, the discussion in excess of protective headgear continues to surface. Soon after viewing information displaying that folks desired a helmet that was fashionable and secure, the two designers’ solution seemed to request the impossible – to make an “invisible” helmet. With the physical appearance of a easy scarf or collar, they created the Hövding, which, triggered by an impending crash, deploys an inflatable helmet that covers the wearer’s head and neck.
It operates by tracking the velocity and place of the user via gyroscopes and accelerometers created into the collar. When a cyclist crashes or falls, they move in distinct methods, and when the sensors choose up the movements indicative of a crash, the airbag is deployed using helium. The airbag itself is made from a heavy-duty nylon that envelops the entire head like a hood, protecting these areas most vulnerable in a crash. In truth, exams have proven that the Hövding absorbs shocks 3 times greater than normal helmets.
But the tech isn’t going to just finish with the crash. Whilst the helmets incorporate the necessary sensors to predict a fall, they also capture data quickly just before and in the course of the collision, like a mini-black box. This information can then be utilized by the crew to better analyse genuine-existence situations and is extra to the increasing body of data utilized to increase the helmet’s predictive capability.
With only a single use per helmet, and retailing at €400 each and every, it is plainly aimed at the high-end urban cyclist. But with the international industry for cycle elements and equipment really worth an estimated€36.4bn, the pair have tapped into a very productive seam.
Charles W Hull
3D printer
From parts of a jet plane to human kidneys, the employs for 3D printers are seemingly boundless. But it was to conquer a far simpler dilemma that in 1983 Charles W Hull created the 1st 3D printed object – an optometrist’s cup.
Hull’s difficulty, he says, was that “it took a lengthy time to prototype plastic parts which had been at some point going to be plastic moulded”. It was a convoluted method in which he would have to send various patterns to different producers and, even then, “it would get six weeks or two months and you’d get your sample piece back and normally it would not be very correct”, meaning he’d have to start the total method yet again.
Even though employing UV light to apply thin plastic veneers to table tops, Hull had a thought: could he use this engineering to decrease the time it took to mould and manufacture tiny plastic prototypes from months to minutes? He set about attempting.
“I had the basic idea, and so exactly where I worked I set up a lab in the back,” he says. “Almost certainly, I will not bear in mind precisely, but for a year… at nights and weekends, I finally acquired it all doing work.”
By overlaying 1000′s of these thin veneers, Hull identified that he could use the UV light to harden successive layers of liquid plastic to generate objects of virtually any shape or complexity. He has termed this approach “stereolithography”.
Thirty years on and Hull is now the father of an industry really worth $ two.2bn. “I realised the possible for the dilemma I was solving, but I definitely did not realise the scope that 3D printing was going to consider,” he says.
While the technology has been used for years in the commercial sector, notably in manufacturing by the Ford Motor Business throughout the 1990s, Hull is in no way stunned that it is taken this lengthy to break into the public sphere.
“Inventions take a long time to go mainstream that’s sort of typical,” says Hull. “I’d advised my wife that it was going to take 25 years just before everyone is aware of about this and it truly is been around thirty.”
Nonetheless, it truly is been the previous number of years that have observed the attain of the 3D printer multiply and this is what excites the inventor.
“The medical applications are truly interesting – surgical implants, prostheses and tenfold [other] applications.” In the discipline of medication, the technological innovation has been seized upon in a way Hull in no way anticipated: from printing living stem cells, blood vessels and skin to moulding personalised dental implants, the industry is swiftly expanding.
This isn’t the only advancement that excites Hull. “The move into direct manufacturing has been going on for all around 5 many years now, and I feel it is really fascinating simply because that is what I originally worked on.”
But can we count on every single home to have a 3D printer in the future?
“Private printers are also swiftly expanding, so it’s really a moving field in all directions. I am not a futurist sort of man or woman, but I would assume above time that it truly is just going to be true frequent.”
Who will be crowned Europe"s prime inventor?
