The demand for portable wireless battery chargers is increasing as the electronic gadgets in daily life need an uninterrupted power supply
Researchers at Sejong University in South Korea have developed a new infrared wireless charting system that transmits the power over a distance of up to 30 meters.
Researchers found a method called distributed laser charging for providing safe high-power illumination with less light loss.
The new Infrared wireless charging system is made up of two components, a transmitter, and a receiver.
The transmitter is an optical power source used for producing a beam of infrared light with a wavelength of 1550 nm.
The receiver is made up of a retroreflector (photovoltaic cell) that transforms the optical signals into electric energy.
