3D printers start to build factories of the future
Posted by Derick Lee in categories: 3D printing, futurism, robotics/AI
As this example shows, 3D printing has come a long way, quickly. In February 2011, when The Economist ran a story called “Print me a Stradivarius”, the idea of printing objects still seemed extraordinary. Now, it is well established. Additive manufacturing, as it is known technically, is speeding up prototyping designs and is also being used to make customised and complex items for actual sale.
SLOWLY but surely the sole of a shoe emerges from a bowl of liquid resin, as Excalibur rose from the enchanted lake. And, just as Excalibur was no ordinary sword, this is no ordinary sole. It is light and flexible, with an intricate internal structure, the better to help it support the wearer’s foot. Paired with its solemate it will underpin a set of trainers from a new range planned by Adidas, a German sportswear firm.
Adidas intends to use the 3D-printed soles to make trainers at two new, highly automated factories in Germany and America, instead of producing them in the low-cost Asian countries to which most trainer production has been outsourced in recent years. The firm will thus be able to bring its shoes to market faster and keep up with fashion trends. At the moment, getting a design to the shops can take months. The new factories, each of which is intended to turn out up to 500,000 pairs of trainers a year, should cut that to a week or less.

New 3D chip combines computing and data storage
Posted by Klaus Baldauf in categories: biotech/medical, engineering, nanotechnology, robotics/AI
As embedded intelligence is finding its way into ever more areas of our lives, fields ranging from autonomous driving to personalized medicine are generating huge amounts of data. But just as the flood of data is reaching massive proportions, the ability of computer chips to process it into useful information is stalling.
Now, researchers at Stanford University and MIT have built a new chip to overcome this hurdle. The results are published today in the journal Nature, by lead author Max Shulaker, an assistant professor of electrical engineering and computer science at MIT. Shulaker began the work as a PhD student alongside H.-S. Philip Wong and his advisor Subhasish Mitra, professors of electrical engineering and computer science at Stanford. The team also included professors Roger Howe and Krishna Saraswat, also from Stanford.
Computers today comprise different chips cobbled together. There is a chip for computing and a separate chip for data storage, and the connections between the two are limited. As applications analyze increasingly massive volumes of data, the limited rate at which data can be moved between different chips is creating a critical communication “bottleneck.” And with limited real estate on the chip, there is not enough room to place them side-by-side, even as they have been miniaturized (a phenomenon known as Moore’s Law).

Researchers create temperature sensor that runs on almost no power
Posted by Shailesh Prasad in categories: computing, materials
Researchers at UC San Diego have developed a temperature sensor that runs on tiny amounts of power — just 113 picowatts, around 10 billion times less power than a watt. The sensor was described in a study recently published in Scientific Reports. “We’re building systems that have such low power requirements that they could potentially run for years on just a tiny battery,” Hui Wang, an author of the study, said in a statement.
The team created the device by reducing power in two areas. The first was the current source. To do that, they made use of a phenomenon that many researchers in their field are actually trying to get rid of. Transistors often have a gate with which they can stop the flow of electrons in a circuit, but transistors keep getting tinier and tinier. The smaller they get, the thinner the gate material becomes and electrons start to leak through it — a problem called “gate leakage.” Here, the leaked electrons are what’s powering the sensor. “Many researchers are trying to get rid of leakage current, but we are exploiting it to build an ultra-low power current source,” said Hui.
The researchers also reduced power in the way the sensor converts temperature to a digital readout. The result is a temperature sensor that uses 628 times less power than the current state-of-the-art sensors.

Study finds hackers could use brainwaves to steal passwords
Posted by Shailesh Prasad in categories: entertainment, robotics/AI, security
Researchers at the University of Alabama at Birmingham suggest that brainwave-sensing headsets, also known as EEG or electroencephalograph headsets, need better security after a study reveals hackers could guess a user’s passwords by monitoring their brainwaves.
EEG headsets are advertised as allowing users to use only their brains to control robotic toys and video games specifically developed to be played with an EEG headset. There are only a handful on the market, and they range in price from $150 to $800.
Nitesh Saxena, Ph.D., associate professor in the UAB College of Arts and Sciences Department of Computer and Information Sciences, and Ph.D. student Ajaya Neupane and former master’s student Md Lutfor Rahman, found that a person who paused a video game and logged into a bank account while wearing an EEG headset was at risk for having their passwords or other sensitive data stolen by a malicious software program.
