Scientists Dovlaped Carbon Nanotub Sensor Chew-Gum

researchers have developed a way to incorporate carbon nano tubes into chewing gum so that the sticky mass can be used as a stretchable, bendable medical sensor. Seems James Bond's next movie gadget?
A team of researchers from the University of Manitoba in Winnipeg chewed Double-mint gum for 30 minutes, soaked it in ethanol to make sure it was clean, then loaded it with carbon nanotubes. The resulting blob was still flexible and bendable and, thanks to the fact that carbon nanotubes can conduct electricity, able to be used as a sensor.

In experiments published in ACS Applied Materials & Interfaces, the team shows that the modified gum works as a smart little strain gauge. That's to say that if you stick two electrodes into its ends and then deform it, the changing voltage between the two points-a result of variation in the sensor's electrical resistance-will tell you how much it's stretched by. The sensor's read out is linear when the gum stretches by 200 percent, and provides useful results until it's deformed by as much as 530 percent.
The voltage changes quickly with deformation, too, so the team reckons that a strip of the gum could be applied across part of the human chest to neatly detect breathing. The fact that the gum is entirely flexible could make it an attractive alternative to most existing medical sensors, that are typically made from metal or plastic, too, because it can more easily move with the body of a patient.
And the best bit? Fortune reports that the sensor could cost as little as $3 to make. Most of that'll be for the nanotubes, rather than the gum, we guess.

LG’s first flexible OLED phone due before the year is out

LG plans to launch a flexible OLED smartphone before the end of the year, the company’s VP of mobile has confirmed, though it’s unclear to what extent the work-in-progress handset will actually flex. The OLED panel in question is the handiwork of LG Display according to VP of LG mobile Yoon Bu-hyun, the WSJ  reports, with the proposed device set to launch sometime in Q4. LG Display’s work on flexible OLEDs has been underway for some time, though the company’s efforts have perhaps been overshadowed somewhat by rival Samsung’s YOUM development. Last year, according to a Korea Times report, LG Display was preparing for

Bing Apps for Windows 8 get major updates

Late least year, Microsoft rolled out a half dozen Bing Apps for Windows 8 users, each one focused on a specific category, such as travel and sports. The apps were designed to offer “immersive vertical experiences,” and now, about six months later, a big line of updates for them is being pushed out. Users can grab the updates now by heading into the Windows Store and selecting the updates notification.
Flexible displays are the Future of IT Industry! A part from 4k and smart home appliances, the CES 2013 saw a lot of attention being drawn towards bendable, flexible displays. The elasticised display idea isn’t something new as we have seen hoards of device concepts being crafted around flexible, bendable and even foldable displays. These concept devices give us a futuristic feel, be it a flexible phone to be worn around the wrist or a phone that opens up to turn into a tablet or PSP-like device. But how far is this future? Nokia has been toying with the idea ever since we remember. The technology sounds very fascinating and the possibilities and the extent to which bendable displays could be used are vast and leave us spellbound. However, these have always been concepts and we haven’t seen any device materialise in the real world. There have been several technologies that were conceived in these years and all have been put to their practical use. But the bendable d
