Apple exploring induction, solar and motion charging for curved-glass iWatch

Apple is testing a variety of different charging methods for its "iWatch" smart watch project, according to a The New York Times report. At the top of Apple's list appears to be induction charging, allowing users to recharge their watches wirelessly.
 
For its wristwatch, Apple has been testing a method to charge the battery wirelessly with magnetic induction, according to a person briefed on the product. A similar technology is already used in some Nokia smartphones — when a phone is placed on a charging plate, an electrical current creates a magnetic field, which creates voltage that powers the phone.

 
Another test at Apple has involved charging the battery through movement, a method that is already used in many modern watches. A person’s arm swinging could operate a tiny charging station that generates and pushes power to the device while walking, according to a patent filed by Apple in 2009.
