Samsung and Apple stepped up their game by introducing wireless charging technology, where your phone automatically charges when laying on a specifically designed electronic pad. But researchers at the UW might have just invented the next great phone charging breakthrough: lasers.
The first challenge they faced was how to charge a phone via laser without harming people in the process. Their system includes one main charging beam surrounded by four safeguard beams that will shut down the stronger charging beam when their stream is broken to avoid injury. The second key component is the receiver that attaches onto the back of the phone to convert the energy provided by laser into electrical energy, charging the cellphone’s battery.
