Xerox ink will print circuits


Xerox has announced a breakthrough in printable circuits. They’ve developed a conductive ink called “silver bullet” that can be printed on many different types of substrate to create circuits. The key part of the new ink is its lower melting point. Plastic film substrate melts at 150 degrees Celsius but the ink is liquid when ten degrees cooler to avoid damaging the film. This begs the question: how do you then solder components to the circuit?

Xerox Scientists Develop "Silver Bullet" Needed to Replace Silicon Circuits with Low-Cost, Durable Plastic

Integrated circuits are made up of three components - a semiconductor, a conductor and a dielectric element - and currently are manufactured in costly silicon chip fabricating factories. By creating a breakthrough silver ink to print the conductor, Xerox has developed all three of the materials necessary for printing plastic circuits.

Muscle-Computer Interface

The Future of Video Game Input: Muscle Sensors

Electromyography (EMG) sensors can decode muscle signals from the skin's surface as a person performs certain gestures. Researchers attached such sensors to their forearms, and built a gesture recognition library by monitoring muscle signals related to each gesture. The project emerged as a collaborative effort between Microsoft, University of Washington in Seattle, and the University of Toronto in Canada.

Muscle-Bound Computer Interface

Forearm electrodes could enable new forms of hands-free computer interaction.

The new muscle-sensing project is "going after healthy consumers who want richer input modalities," says Desney Tan, a researcher at Microsoft. As a result, he and his colleagues had to come up with a system that was inexpensive and unobtrusive and that reliably sensed a range of gestures.

Muscle-Computer Interfaces

Muscle-computer interfaces directly sense and decode human muscular activity rather than relying
on physical actuation or perceptible user actions. Using a wireless EMG armband, we have shown
relatively high accuracies decoding simple finger gestures both when the arm is rested on a surface,
but also when the gestures are performed in free space.

Bridgestone Color E-Paper


Bridgestone Corp announced an electronic paper (e-paper) device based on its "Quick-response Liquid Powder" Oct 26, 2009.

The company expects that the device will be used for browsing electronic books and electronic data. It will be tested with the assistance system for liaison officers at Kansai Urban Banking Corp from the spring of 2010.

According to ePaperCentral, “unlike other e-paper devices like the Kindle and Sony’s 505/700, the Bridgestone model does not use E Ink based technologies. Instead, it uses a powerful technology built in house that could completely revolutionize e-paper called QR-LPD.”

Bridgestone Color E-paper

The Technology

The technology behind the screen itself is based on Bridgestone’s own QR-LPD electronic powder, which provides the quick rendering of black and white images that are as clear and paper-like as E Ink’s technology, and uses about the same battery life. Color is provided by a series of filters that go over each individual pixel that create the impression of a high definition, true color display.

The touch screen surface is provided by a WACOM tablet, much like the touch screen surface used in Sony’s PRS 700 and the IRex Iliad. As you can see in the example videos, the touch screen updates really quickly, but the actual full display refresh can be very slow. Depending on the model and the image displayed, the full screen refresh can be anywhere from .8 seconds to a full 15 seconds.

Scientists Enslave Bacteria to Power Tiny Microsized Motor

Italian scientists from the University of Rome managed to harness free floating E. coli bacteria to turn a tiny crankshaft. Although potential uses for such a tiny and unusual motor drive are not yet clear, no doubt interesting applications in medicine and life sciences should present themselves over time.

Micromotors pushed by biological entities constitute a fascinating way to
convert chemical energy into mechanical work at the micrometer scale. We show
that a properly designed asymmetric object can be spontaneously set into the
desired motion when immersed in a chaotic bacterial bath.

Digital Rosetta Stone

Storage for the Millennium


If people can read this story a millennium from now, they may have Tadahiro Kuroda to thank. Kuroda, an electrical engineering professor at Keio University in Japan, has invented what he calls a "Digital Rosetta Stone," a wireless memory chip sealed in silicon that he says can store data for 1,000 years.

Kuroda’s Rosetta stone will be a stack of four thin wafers, each one 15 inches in diameter and roughly 12-thousandths of an inch thick, embedded with 1,100 tiny chips. Together, says Kuroda, the four wafers will have 312 gigabytes of memory, the equivalent of 480 standard cds. The wafer stack is sealed in silicon dioxide, which keeps the humidity below 2%, preventing corrosion.

Kuroda's method: Instead of moving data as electrons through wires, as occurs in standard semiconductors, Kuroda’s sealed stack of wafers allows information to be beamed wirelessly on radio waves. This is a variation on radio-frequency identification technology, used in everything from scannable passports to inventory tracking.

Why extremists tend to dominate debates

Why Extremist Views Dominate

A new study suggests a possible reason: People with extreme views seem more willing to share their opinions than others, but only if they believe, even falsely, that their views are popular.

Extremists Assume Majority Status When Sharing Opinions

Extremists More Willing To Share Their Opinions

Those that take the extreme version of their group’s viewpoint may believe that they actually represent the true views of their group. “When people with extreme views have this false sense that they are in the majority, they are more willing to express themselves,” said Kimberly Rios Morrison, co-author of the study and assistant professor of communication at The Ohio State University (OSU).

The key is that the extremists have to believe that more people share their views than actually do, the research found.
