A new advance in technology may soon may allow electricity to be transmitted wirelessly through the same kind of magnetic fields that Wi-Fi uses. Using coils attached to a power source that generate a magnetic field will allow electricity to be transferred wirelessly to devices close enough. This could allow devices to be charged automatically just by sitting in the same room. Wireless technology can also lead to a lot of upgrades to current medical procedures and implants that need invasive recharging. A team working towards wireless electricity has recently come up with wirelessly rechargeable batteries that they hope is just the beginning of the wireless revolution.
