process where electrons are stripped away from their normal locations in atoms and molecules. It can permanently damage biological tissues including DNA‚ the genetic material. The energy levels associated with radiofrequency energy‚ including both radio waves and microwaves‚ are not great enough to cause the ionization of atoms and molecules. Therefore‚ RF energy is a type of non-ionizing radiation. Other types of non-ionizing radiation include visible light‚ infrared radiation (heat) and other forms

termed as Witricity. Witricity principle works by using coupled resonant objects for carrying of electricity to objects without use of wires. This system consists of an electric transmitter and a receiver. The working principle of receiver is just as radio receiver where the device needs to be in the range of transmitter. Witricity produces electricity with the use of resonant magnetic field and simultaneously stops any wastage of power. With this system in place we can achieve transmission up to a range
