March 18, 2014 9:57 am | News | Comments

Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket. One approach they are trying involves designing circuits based on electronic fibers, known as carbon nanotubes, instead of rigid silicon chips. But reliability is essential.

Researchers devise stretchable antenna for wearable health monitoring

March 18, 2014 9:13 am | by Matt Shipman, News Services, North Carolina State Univ. | News | Comments

Researchers from North Carolina State Univ. have developed a new, stretchable antenna that can be incorporated into wearable technologies, such as health monitoring devices. The researchers wanted to develop an antenna that could be stretched, rolled or twisted and always return to its original shape, because wearable systems can be subject to a variety of stresses as patients move around.

South By Southwest: Secrets, spying, chef Watson

March 11, 2014 11:49 am | by Barbara Ortutay, AP Technology Writer | News | Comments

FOMO—or the fear of missing out—is a common complaint at the South By Southwest Interactive festival in Austin, Texas each year. It's here, after all, that "Girls" creator Lena Dunham spoke on Monday at the same time that NSA whistleblower Edward Snowden gave a teleconferenced talk. All the while, IBM showed off the capabilities of cognitive computing in a language anyone could understand: food.

Bending the light with a tiny chip

March 11, 2014 7:56 am | by Jessica Stoller-Conrad, Caltech | News | Comments

Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your phone projects a bright, clear image onto a wall or a big screen. Such a technology may be on its way, thanks to a new light-bending silicon chip developed by researchers at the California Institute of Technology.

Scientists build thinnest-possible LEDs to be stronger, more energy efficient

March 10, 2014 1:11 pm | by Michelle Ma, Univ. of Washington | News | Comments

Most modern electronics, from flatscreen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy efficient.

March 7, 2014 7:50 am | News | Comments

Using an inexpensive inkjet printer, Univ. of Utah electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast components in electronic devices, make wireless technology faster or print magnetic materials.

Measuring wind turbines remotely

March 5, 2014 2:57 pm | News | Comments

The rotor and mast of a wind turbine can oscillate and this plays a big role in equipment development and maintenance. Up to now, this analysis has only been possible at discrete points located directly on equipment. Engineers are now using modern information technology to remotely measure the oscillatory pattern over the entire structure of the facility from several hundred meters away.

A complete medical check-up on a chip

March 4, 2014 3:56 pm | News | Comments

About the size of a stapler, this new handheld device developed in Switzerland is able to test a large number of proteins in our body all at once. This optical “lab on a chip” is compact and inexpensive, and it could offer the possibility of quickly analyzing up to 170,000 different molecules in a blood sample.

Promise and peril in an ultra-connected world

March 3, 2014 11:41 am | by Anick Jesdanun, AP Technology Writer | News | Comments

We're in the beginning of a world in which everything is connected to the Internet and with one another, while powerful yet relatively cheap computers analyze all that data for ways to improve lives. At least that's the vision presented this past week at the Mobile World Congress wireless show in Barcelona, Spain, and some of that vision is already available or promised by the end of the year.
