Cellphones emit low frequency electromagnetic radiation which has adverse effects on human body. Though the exact results of radiation when exposed to body are not known, but the area of brain closer to the cellphone (while in use ) absorbs 48% to 68% of radiation, not only affecting health but also lowering power of transmitted signal. A company called Pong has created a unique smartphone case which reduces radiation absorption by about 95%. The case is made of a material used in construction of NASA spacecrafts and works in-hand with the cellphone's internal antenna to redirect radiations away from user's body.

The technology also helps in improving signal strength and battery life. Since most of the radiations are redirected away and least is lost in absorption by human body, they are received by the cellular towers leading to an increase in signal strength. Also most of the battery is drained in search of signals, increased signal strength by Pong cases result in an improved battery life.
