Apple iWatch could charge itself from wrist movement

Apple's next device, the iWatch, could be powered by movements of the wrist, according to a patent filing published today.

Apple's next device, the iWatch, could be powered by movements of the wrist, according to a patent filing published today.

 
The patent, numbered 20130044215, is entitled “Bi-Stable Spring with Flexible Display” and covers: “A wearable accessory device is disclosed. The wearable accessory device includes a flexible display coupled to a bi-stable spring. Coupling the display to the bi-stable spring allows the accessory device to be easily worn in a number of convenient locations.”
 
Perhaps the most interesting idea presented in the patent is the concept of charging the battery of the iWatch through the kinetic energy generated from everday wrist movements, which could potentially keep it powered indefinitely, a major boon for power-hungry modern devices.

The patent also covers the ability to listen to music and make calls, making it an effective replacement for an iPhone. Apple may be reluctant to give it too much functionality, however, or it could cannibalise sales of its other devices. One option is to make it wirelessly access data from the iPhone a user is carrying, as the patent suggests will be the case. This will ensure consumers buy both devices, but that could also render it less attractive.
 
The patent was originally filed on 17 August, 2011, so Apple has clearly been working on this for quite some time. With Google readying Glass for release, and Apple losing smartphone market share to Samsung, the Cupertino, California-based firm will need to up the ante to maintain its image as a major innovator. With 100 designers working on the iWatch, this is clearly Apple's next big thing.
