Your phone may not cause cancer, but it does emit enough electromagnetic energy to power a small device. Concepter’s Lune smartphone case detects when you’re receiving a call based on the wavelength of your cell signal and shows a green light to alert you, using your phone’s energy field as its only power source. We had a chance to test the Lune at CES 2014 and were amazed with its unique use of energy and radio waves.
The version of the Lune case we saw was made for an iPhone with a simple black design and a light ring around the Apple logo. However, Concepter told us that it will also make versions for other phones and that the final version will have different lights for call and SMS message alerts.

Concepter will be putting the Lune on kickstarter in the next few weeks with an estimated price of aroound $35. We look forward to seeing what this innovative product becomes when in its final form.
