Apple Is Experimenting With Solar, Inductive And Motion Charging For iWatch

According to the New York Times and their sources Apple is currently testing a method to charge the battery of the rumored iWatch with magnetic induction. And this could be exactly what Apple needs to make it stand out from an ever crowded market of smartwatches.


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.

Apple has also experimented with new power-charging methods for a potential smartwatch, people close to the efforts said, though such experiments are years from becoming a reality. The watch is expected to have a curved glass screen, and one idea is to add a solar-charging layer to that screen, which would give power to the device in daylight, they said.

Last week we reported that with a Sapphire glass display the iPhone could feature solar-charging capabilities by embedding ultra-thin solar cells onto sapphire glass display. When you think about it, however, the iWatch would be a much better candidate. And as such Apple’s new plant in Mesa, Arizona, which could be operational by February could indeed be making these solar-charging sapphire glass displays.

Reportedly Apple is also experimenting with charging the battery with movement utilizing an old technology called piezoelectricity.

Another experiment 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.

Although all of this charging technology sounds great unfortunately it is still years away according to the report, but it is a glimpse into the future nonetheless.
