Engineers develop practical way to make artificial skin

Posted by in categories: chemistry, computing, cyborgs, wearables

Chemical engineer Zhenan Bao and her team of researchers at Stanford have spent nearly two decades trying to develop skin-like integrated circuits that can be stretched, folded, bent and twisted — working all the while — and then snap back without fail, every time. Such circuits presage a day of wearable and implantable products, but one hurdle has always stood in the way.

Namely, “How does one produce a completely new technology in quantities great enough to make commercialization possible?” Bao said. Bao and team think they have a solution. In a new study, the group describes how they have printed stretchable-yet-durable integrated circuits on rubbery, skin-like materials, using the same equipment designed to make solid silicon chips — an accomplishment that could ease the transition to commercialization by switching foundries that today make rigid circuits to producing stretchable ones.


Stanford researchers show how to print dense transistor arrays on skin-like materials to create stretchable circuits that flex with the body to perform applications yet to be imagined.

Cheap, sustainable, readily available plasma tech could replace rare iridium

Posted by in categories: chemistry, computing, mobile phones, sustainability, transportation

A team led by a researcher from the University of Sydney has developed a low-cost, sustainable, and readily available technology that can dim the screens of electronic devices, anti-reflection automobile mirrors, and smart architectural windows at a fraction of the cost of current technology.

It would replace one of the world’s scarcest—yet highly ubiquitous in use—modern materials: indium. A rare chemical element, that it is widely used in devices such as smartphones and computers, windscreen glass and self-dimming windows.

Although small amounts are used to manufacture smart screens, indium is expensive as it is hard to source; it naturally occurs only in small deposits. Industrial indium is often made as a byproduct of zinc mining, which means a shortage could occur if demand for optoelectronic devices—such as LCDs and touch panels—ramps up.

Chip Shortage Reaches Smartphone Makers

Posted by in categories: computing, mobile phones, transportation

SEOUL—The smartphone industry is showing battle scars from the world-wide chip crunch.

Shipments are slowing and customers are seeing their first significant price increases in years. Some companies have had to scale back production and delay new releases. All this has halted what had been a strong start to the year.

Smartphone makers, for much of the year, avoided the parts disruptions faced in the auto, personal computer and home-appliance industries. Phone manufacturers purchase key parts roughly a half a year in advance, but now those stockpiles have shrunk.

Taiwan semiconductor company plans to build U.S. factory to meet sustained chip demand

Posted by in categories: biotech/medical, computing, mobile phones

TAIPEI —Taiwan Semiconductor Manufacturing Co Ltd (TSMC) signalled on Thursday plans to build new factories in the United States and Japan, riding on a pandemic-led surge in demand for chips that power smartphones, laptops and cars.

TSMC, which posted record quarterly sales and forecast higher revenue for the current quarter, said it will expand production capacity in China and does not rule out the possibility of a “second phase” expansion at its $12 billion factory in Arizona.

The world’s largest contract chipmaker and a major Apple supplier also said it is currently reviewing a plan to set up a speciality technology wafer fabrication plant, or fab, in Japan.

NASA revives ailing Hubble Space Telescope with switch to backup computer

Posted by in categories: computing, space

Hubble is back!


The Hubble Space Telescope has powered on once again! NASA was able to successfully switch to a backup computer on the observatory on Friday (July 16) following weeks of computer problems.

On June 13, Hubble shut down after a payload computer from the 1980s that handles the telescope’s science instruments suffered a glitch. Now, over a month since Hubble ran into issues, which the Hubble team thinks were caused by the spacecraft’s Power Control Unit (PCU), NASA switched to backup hardware and was able to switch the scope back on.

Tapping into the Brain to Help a Paralyzed Man Speak

Posted by in categories: biotech/medical, computing, neuroscience

He has not been able to speak since 2003, when he was paralyzed at age 20 by a severe stroke after a terrible car crash.

Now, in a scientific milestone, researchers have tapped into the speech areas of his brain — allowing him to produce comprehensible words and sentences simply by trying to say them. When the man, known by his nickname, Pancho, tries to speak, electrodes implanted in his brain transmit signals to a computer that displays his intended words on the screen.

His first recognizable sentence, researchers said, was, “My family is outside.”

Hobbled Hubble Telescope Springs Back To Life On Its Backup System

Posted by in categories: computing, space

“There was cheering in the control center” when word came that NASA had brought a key computer back, says James Jeletic, the Hubble project’s deputy project manager.


The Hubble Space Telescope is returning to operation more than a month after its original payload computer shut down. NASA said it has successfully switched over to its backup computer — and while the process of bringing the system back online is slow, the agency has started to bring science instruments out of “safe mode.”

“There was cheering in the control center” on Thursday night when word came that NASA had managed to restore the payload computer, James Jeletic, Hubble’s deputy project manager, told NPR.

A noninvasive test to detect cancer cells and pinpoint their location

Posted by in categories: biotech/medical, computing, engineering, nanotechnology

Most of the tests that doctors use to diagnose cancer — such as mammography, colonoscopy, and CT scans — are based on imaging. More recently, researchers have also developed molecular diagnostics that can detect specific cancer-associated molecules that circulate in bodily fluids like blood or urine.

MIT engineers have now created a new diagnostic nanoparticle that combines both of these features: It can reveal the presence of cancerous proteins through a urine test, and it functions as an imaging agent, pinpointing the tumor location. In principle, this diagnostic could be used to detect cancer anywhere in the body, including tumors that have metastasized from their original locations.

“This is a really broad sensor intended to respond to both primary tumors and their metastases. It can trigger a urinary signal and also allow us to visualize where the tumors are,” says Sangeeta Bhatia, the John and Dorothy Wilson Professor of Health Sciences and Technology and Electrical Engineering and Computer Science at MIT and a member of MIT’s Koch Institute for Integrative Cancer Research and Institute for Medical Engineering and Science.
