Soon, wrap your smartphone on the wrist

Soon you may be able to use your smartphone on your wrist or bend your computer to fit in your pocket! Researchers have taken a step towards more flexible devices by fabricating a thin film that keeps her even when very curved electric and magnetic properties useful.

Flexible electronics have been difficult to manufacture because many materials with useful electronic properties tend to be rigid.

Researchers have addressed this problem by taking small pieces of material such as silicon and embedded in the flexible plastic.

A team of physicists and engineers from South Korea took the same approach with bismuth ferrite (BiFeO3) - one of the most promising materials whose properties can be controlled with a magnetic field, and vice versa.

These materials are called multiferroic and attract interest for applications such as energy efficient, instant-on computing.

The researchers synthesized bismuth ferrite nanoparticles and mixed in a polymer solution. The solution was dried in a series o…

iOS 8 How to: Monitor and track your battery usage

Have you ever wondered how much your battery is being used? Or have you ever wondered why sometimes when you use certain applications dramatically drains the battery? New in iOS 8 Configuration application is the ability to track usage of the battery for each application you have installed on your device. This method is very similar to track your cellular data usage.  In iOS 7, which shows how much the battery has been used and how long the battery was on alert since last full charge, but does not define or describe how it was made. To monitor and track your battery usage on iOS 8, ​​first go to Settings.

Then tap on General and after use.





With iOS 8 by default, the battery percentage off. I recommend turning it on, and they immediately give you a better idea of what your battery life is so contrary to the image of the battery.

Touching on battery usage, is displayed the first time since last full charge. This information was available in iOS 7 Shows you use, how long has actually b…
