High performance transistors created on flexible plastic sheets

Using a technique known as nanoimprint lithography, researchers at the University of Wisconsin-Madison and partners have created a breakthrough method to allow the simple manufacture of inexpensive, high-performance, wireless-capable, flexible Metal Oxide Semiconductor Field Effect Transistors that overcome many of the operation problems encountered in devices manufactured using standard techniques. Created on large rolls of pliable plastic, these MOSFETs could be used to make a host of devices ranging from wearable electronics to bendable sensors.

Cracking a few eggs to make electronics that dissolve

Durability is often touted as the hallmark of good electronics, but sometimes you want components that don't last all that long. For example, it would be handy if microelectronic systems that delivered drugs to various parts of the body dissolved after their task was done. Or if sensors that monitor pollution simply dissolved after they were finished reporting, rather than contributing to even more environmentally-damaging material. A team of researchers from the UK and China has just figured out how to create one such chip out of eggs.Read More

Google Fiber lights up another big city

Google Fiber officially launched in its fifth American city on Wednesday, when the gigabit broadband service became available in one Nashville, Tennessee neighborhood. Right now, Fiber is only available in four apartment buildings near the city's famed Music Row neighborhood, but expansion is planned across the city. Read More

Circuit Classics revive a golden age of electronics design

Aside from being a treasure trove of information for budding electronics engineers from the 1980s on, the down-to-earth style of Forrest M. Mims' Engineers' Notebook and Getting Started in Electronics series of books was a large part of their appeal. Now a crowdfunding project is looking to bring back some of that original charm by producing a limited set of working circuit boards in the Mims' style, replete with accompanying explanations and a wooden stand to display these electronic works of art.Read More

​Review: Flicks portable boombox packs a projector

When the boombox hit popular culture over 30 years ago, it brought the party outside. For the first time it was convenient to have loud, high-quality sound anywhere you wanted it without needing AC power or having to hook up complicated sound systems. With the proliferation of wireless Bluetooth speakers and the MP3 format, boomboxes have gone the way of the mullet haircut, but a new version called Flicks from Dashbon is bringing it back with a very 21st-century addition: a projector. We got to try one out.Read More

Flexible e-skin display is thinner than Saran wrap and tracks blood oxygen levels

From displays that curve to screens that swerve, flexible electronics is fast developing area of technology that promises to put a new twist on the way we absorb information. Bending televisions are an early example of this being adapted to the consumer world, and if a team of Japanese researchers has its way electronic skin (e-skin) won't be all that far behind. The team's new durable, flexing OLED display prototype is less than one quarter the thickness of Saran wrap and can be worn on the skin to display blood-oxygen levels, with the developers working to afford it other health-monitoring abilities, too.Read More

Nanotube circuits self-assembled and powered at a distance via "Teslaphoresis"

Using a powerful electric force emitted by a Tesla coil, scientists at Rice University have made carbon nanotubes self-assemble to form a circuit linking two LEDs and then used the energy from that same field to power them. According to the researchers, the manipulation of matter on this scale has never before been observed and they've dubbed this phenomenon of remotely moving and assembling the nanotubes "Teslaphoresis."Read More

Precise embroidered circuits bring next-gen smart clothing closer to reality

From sweat-sensing wristbands to electrode-embedded workout suits, new innovations in smart clothing are coming thick and fast. Now, Ohio State University researchers have made another big breakthrough, managing to create embroidered circuits using metallic thread that's just 0.1 mm thick. By embedding different patterns, the tech could be used to create everything from a t-shirt that boosts your cellphone signal, to a hat that tracks brain activity.Read More
