A new smartphone case prototype on display at the Consumer Electronics Show in Las Vegas featured a unique way to signal an incoming call that makes use of the cell phone’s electromagnetic radiation.


Concepter’s Lune smartphone case detects when a call is being received based on the wavelength of the phone’s GSM signal and alerts the user by illuminating a ring of green LEDs on the back of the case, using only the phone’s electromagnetic field as its power source. The company reportedly declined to reveal the inside of the case or further specifics as to how it functions.

Recycled electromagnetic energy is an effective way to provide power to low current electronic circuits. Adapters and gadgets that plug into our smart devices are a great way to employ this technology.

While the prototype case on display was made for an iPhone, Concepter is planning to make versions for other types of phones, as well as install differently colored LEDs for other notifications such as SMS messages.

The company is expected to place the Lune smartphone case on crowdfunding website Kickstarter later this month. Recycled electromagnetic energy is a great way to provide energy to low power circuits. Adapters and gadgets that plug into our smart devices are a great way to employ this technology.
