Startup Pi develops first wireless charger

A new company from the Silicon Valley, the startup Pi, claims that it has developed the first wireless charger in the world, eliminating the need for cords and mats.

The Pi chargers, about the size of a small table vase, use the standard charging technology implemented in wireless charging of Apple or Android smartphones, AFP reports.

However, instead of cords or mats, the conical creation charges smartphones with magnetic waves.

– Magnetic fields are an ideal way to safely send energy to portable electronics – said Pi chief technology officer Lixin Shi, who co-created the charger with John MacDonald.

The trick was bending magnetic waves to find smartphones, the co-founders said during a presentation for an AFP journalist at the TechCrunch Disrupt startup scrum in San Francisco.

– The hard part was figuring out how to make magnetic charging more flexible, multi-device and extend its useful range – Shi said and added that it took them over a year to complete the mathematical proof that makes it all possible.

The pair figured out how to shape the magnetic field so energy could be beamed to smartphones placed or in use within a foot of a Pi.
