New Portable Device Counts White Blood Cells Through the Skin
Posted by Shailesh Prasad in categories: bioengineering, biotech/medical, electronics, information science
Madrid, Spain (Scicasts) — A novel way to count white blood cells without a blood test, simply by applying a small device on the fingertip, is being developed by a team of young bioengineers.
The technology, that combines an optical sensor with algorithms, has already three prototypes on the go and is specially designed to be used on chemotherapy patients, who could know their immune system levels in real time. It could also serve to detect serious infections.
A group of young bioengineers from various countries, including Spaniard Carlos Castro, is developing a portable device capable of counting white blood cells in real time, without requiring a blood test. The system includes an innovative optics sensor through the skin that can observe white cells as they flow past a miniature lens. This new device could be applied to improve the treatment of patients who are left immunosuppressed after chemotherapy treatments and to prevent sepsis.

Scientists paint quantum electronics with beams of light
Posted by Shailesh Prasad in categories: computing, electronics, materials, quantum physics
A team of scientists from the University of Chicago and the Pennsylvania State University have accidentally discovered a new way of using light to draw and erase quantum-mechanical circuits in a unique class of materials called topological insulators.
In contrast to using advanced nanofabrication facilities based on chemical processing of materials, this flexible technique allows for rewritable ‘optical fabrication’ of devices. This finding is likely to spawn new developments in emerging technologies such as low-power electronics based on the spin of electrons or ultrafast quantum computers.
The research is published today in the American Association for the Advancement of Science’s new online journal Science Advances, where it is featured on the journal’s front page.

Meet the laundry-folding washing machine of our lazy-ass future
Posted by Shailesh Prasad in categories: electronics, habitats, robotics/AI
Socks are the hardest. For a future washing machine that washes, dries and then folds the results, it’s one of the small barriers that remains in that latter stage. But as a research project that started back in 2008, Laundroid is finally getting there. Next year, the collaboration between housing firm Daiwa House, electronics company Panasonic and Seven Dreamers will start offering preorders, the year after that ‘beta’ machines, then folding machines for big institutions, with event full retail planned the year after that — we’ll be in 2019 by then. (That said, the all-in-one model is still at the in-development stage). There’s no price and the presentation we saw added in a bunch of mosaic filtering on top as the shirt gradually got folded so you couldn’t see how the thing actually works. But that’s okay. We can wait. It’s not going to stop us waiting our chore-dodging dreams to come true.
While the video teaser above gives you pretty much nothing of substance, at the on-stage demonstration, we saw a just-washed tee take a matter of minutes for the internal tech to sort, identify and fold. The tech involved is separated into two very separate parts: image analysis and robotics. With a hypothetical bundle of clothes, each item demands different folding (we’re going to say) techniques, so the machine needs to figure what that soft lump of cloth is, then prime it for folding. The presentation here at CEATEC elaborated (if only lightly) on the stages it’s taken to get to here: it’s been a pretty long journey.

The topolariton, a new half-matter, half-light particle
Posted by Shailesh Prasad in categories: electronics, particle physics
A new type of “quasiparticle” theorized by Caltech’s Gil Refael, a professor of theoretical physics and condensed matter theory, could help improve the efficiency of a wide range of photonic devices—technologies, such as optical amplifiers, solar photovoltaic cells, and even barcode scanners, which create, manipulate, or detect light.

This Prosthetic Could Restore Memory In Dementia Victims
Posted by Robert James Powles in categories: biotech/medical, cyborgs, electronics, information science, neuroscience
Memory loss is a truly devastating part of dementia, but this invention aims to fix that by bypassing the damage, and repairing long term memory.
Alzheimer’s and dementia are complex diseases, and there’s currently no effective treatment. Given the unpleasant nature of the disease, there’s an urgent need for results. Instead of taking the usual biological route, one team has constructed a prosthetic made up of a small electrode array — which can help re-encode short term memory into long term.
Built using decades of research, the device operates using a new algorithm based on accumulated neural data. New sensory information is normally translated into a quick memory and transported as an electrical signal through the hippocampus, potentially for long term storage. If this region is damaged then the process is disturbed, and new experiences fail to be encoded. Alzheimer’s patients can often remember childhood events, but struggle with recent experiences; specifically because of this hippocampal damage.

This device could harvest energy from the air to power our home gadgets
Posted by Shailesh Prasad in categories: electronics, energy, internet, mobile phones
A British tech company has come up with a new way of powering wearables and smart home devices: a device called the Freevolt, which can harvest the ambient energy from radio waves and turn it into a small amount of electricity for low-energy gadgets to tap into.
As CNET reports, this level of energy can’t keep a smartphone running, but it could be enough to power that remote sensor on your garden gate. If sensors and beacons have a wireless energy source plus wireless connectivity, it opens up more possibilities for kitting out our homes and gardens with these kind of devices.
“Companies have been researching how to harvest energy from Wi-Fi, cellular, and broadcast networks for many years,” Drayton Technologies CEO and chairman, Lord Drayson, said in a press statement. “But it is difficult, because there is only a small amount of energy to harvest and achieving the right level of rectifying efficiency has been the issue — up until now. For the first time, we have solved the problem of harvesting usable energy from a small radio frequency signal.”

This new smart glove can turn sign language into text and speech
Posted by Shailesh Prasad in categories: computing, electronics
Sign language has helped the hearing-impaired communicate for many centuries, way before it was formalised and officially recognised, but this long-standing language of gestures has now been given a 21st-century technological upgrade. Saudi designer and media artist Hadeel Ayoub has invented a smart glove that recognises hand movements and converts them into the relevant text.
Much like Google Translate can give anyone a basic grasp of a foreign language in an instant, this glove is designed to help sign language users make themselves understood by those who can’t usually interpret it.
Five flex sensors sit on the fingers, monitoring how they’re being manipulated, while an accelerometer integrated into the fabric of the glove figures out how the hand is being held and the direction in which it’s pointing. Through three successive prototypes, the glove has been made thinner, lighter, and faster, and the latest version includes a text-to-speech chip to vocalise the words as they’re signed.
