Prof. Yarub Omar Naji, a lecturer from the department of mechatronics engineering at the college of engineering and a Ph.D scholar at the University of Washington has published a research entitled (Investment of the capacitor for wireless transfer of electrical power) in IEEE Journal. This research included, for the first time in history, the use and exploitation of capacitors of electrical and isolated conductive objects, such as the organism’s body or metal structures, for the transmission of ultra-safe power with an efficiency of more than 90% for long distances of more than 1 mm and their delivery to portable electronics in less than 1 mm in size which is indicating that this method is the best one than others previously approved such as electromagnetic induction, radio or ultrasound waves.
