QR codes could generate 3D images on phones – no internet required

By - November 14, 2014 3 Pictures
Whether they're on product packaging, promotional materials or in magazines, most QR codes do the same thing – when a smartphone scans them with its camera, they trigger that phone's web browser to navigate to a given website. In the near future, however, they may be used to securely display 3D images on the user's phone, without even involving the often-untrustworthy internet. Read More

New RF circulator to run rings around old technology

By - November 12, 2014 2 Pictures
In the world of electronic components, there are many devices out there that do their job well and reliably, but are almost never heard of – even though they may be vital to equipment that plays a role in our technology-driven lives. The radio frequency (RF) circulator is just such a device: it has simply done its job as a nondescript box of gubbins buried in radio communications systems, quietly directing radio frequency signals to the places they should go. Now researchers at the University of Texas have given the RF circulator a makeover. Not only is the new prototype smaller, lighter, and cheaper, it's also claimed to be easily adapted to different frequencies on the fly, which is something the old style circulator cannot do.

New technique for generating electricity from mechanical vibrations

By - November 12, 2014
Electrical energy is normally generated through heat, motion, nuclear transformation, or chemical reactions, but now scientists at VTT Technical Research Center of Finland have devised a new method that involves mechanical vibrations. They figured out how to "harvest" the vibrational energy that occurs naturally when two surfaces with different work functions are connected via electrodes, and this energy could potentially be used to power wearables and other low-power electronics.

Coating makes swallowing batteries safer for curious kids

By - November 5, 2014 2 Pictures
It can be a herculean task to get kids to eat their vegetables, but they'll happily chow down on things they aren't supposed to. If one of those things is a button battery, serious injuries can result in the form of burns to the esophagus or tears in the digestive tract. Researchers may not have found a way to stop kids swallowing button batteries, but they have found a way to make such culinary no-nos safer. Read More

Energy-efficient 3D display maintains images without power

By - November 3, 2014
Liquid Crystal Displays (LCDs) are a common and increasingly pervasive method of displaying information for everything from watches to giant TV screens. Though, like most other displays, LCDs require electrical energy to constantly display an image. Researchers from the Hong Kong University of Science and Technology, however, have produced an ultra-thin LCD screen prototype that is not only capable of displaying images without continuous power, but in 3D as well.

Bluesmart smart carry on brings luggage into the 21st century

By - November 1, 2014 5 Pictures
Let’s face it, air travel sucks. You are crammed in a small cylinder at 35,000 feet with a herd of other people like cattle, noshing on junk food a cranky flight attendant pitches at you while hurrying by. Worst of all, you forgot to charge your tablet and now can’t watch all those Marvel movies you wanted to catch up on. A solution could exist to at least this last problem though, courtesy of a new so-called "connected carry-on" called Bluesmart that packs a built-in battery capable of charging your gadgets many times over.
