Lunecase Uses Electromagnetic Energy to Display iPhone Notifications

by

Ukrainian company Concepter today debuted a new Kickstarter project for the Lunecase, a new iPhone case that uses electromagnetic energy emitted from the iPhone to detect and alert users when a text message or phone call is placed.

The Lunecase does does not require a battery or a connection with the phone, but it is able to determine when the iPhone receives an SMS message or a phone call, at which point it lights up an LED on the back of the phone to create a visual notification.

The case is smart enough to tell the difference between the two types of notifications and the LED in the case is powered by energy emitted by the iPhone itself. Eliminating the need for a battery allows the Lunecase to retain a thin form factor while being able to provide notifications. Lunecase was initially shown off at CES 2014, where it received positive reactions.

"Accessories made for the iPhone can sometimes take the beauty and easy functionality away from the phone," said Concepter founder Vlad Tislenko. "Lunecase brings the back of your phone to life and enhances the natural iPhone functionality with no batteries, no cords and no bulk."

Currently, Concepter is creating Lunecases for the iPhone 5/5s and the iPhone 5c.

A limited number of black Lunecases can be preordered on Kickstarter for $30, with a white Lunecase also available for the iPhone 5/5s for a pledge of $39. Personalized engraving is available for $99, and all Lunecases are expected to ship in August of 2014.

My iPhone has a builtin screen that can display the same information and more.

It has not a battery nor a connection? Surely this uses some form of dark sorcery!

I agree that it's a cause of concern that it can be powered by electromagnetic energy released from the phone, but I'm no physicist. Cool technology though.

If your phone didn't emit electromagnetic energy, it wouldn't *work*. That's what radio waves are. It looks/sounds like it's leeching power off your phone's transmit antenna, which 'powers up' when there is an incoming call or text.

If I'm right, I can't imagine this is going to do good things for signal strength/reception, and that'll cause your battery to drain faster.

I agree that it's a cool bit of tech, though. Even if maybe not practical.

This is a little scary - the fact that this case can power its LED off of the background electromagnetic emissions of the iPhone tells you that there is fair bit of energy to exploit there. Makes you wonder if there is a genuine cause for concern.
