Ukranian company Concepter has developed an iPhone case that uses electromagnetic energy emitted from the smartphone to detect and alert users about an incoming call or message. Dubbed Lunecase, the product looks like a normal iPhone case but glows with a special notification icon.

As soon as your phone receives a call or a message, it emits enough electromagnetic radiation to power a small miniscule circuit inside the case, which in turn lights up an LED on the back of the case to create a visual notification. The Lunecase doesn't require a battery or a connection with the smartphone, just snap it on and it's ready to work right away.

What's more, it's smart enough to differentiate between a call and a message, and creates separate notifications corresponding to each. Of course, one limitation is that you would have to get in the habit of setting your phone with the screen side down in order to see the notifications.

"Our top priority was to create a functional and intelligent case that still looked sleek, chic, and preserved the aesthetic lines and contours of the iPhone", said the Lune team.

The case is currently in crowd funding mode on Kickstarter. It was launched yesterday and is already over halfway to the $50,000 goal. The company is currently offering white and black colored Lunecases for the iPhone 5/5S and 5C. You can get one for a minimum pledge of $39.

Shipments are expected to begin in August this year.
