We’ve seen a few patents from Apple that cover flexible components that would be suitable for its much-rumored watch product in the past. Some of which include a couple for flexible displays and another that details a device that changes functionality as it bends. Today we get a look at another patent application from Apple, this time covering battery designs that could very well end up in a flexible or bendable product such as a wristwatch (via PatentlyApple):

While Apple lists a variety of products that could take advantage of the flexible battery designs, it does specifically mention “wristwatches” in the patent application. From the patent drawing above, we can easily see how it could be beneficial for its much rumored iWatch.

As we inch closer to expected fall hardware releases for Apple’s mobile lineup, rumors of an ‘iWatch’ smart watch product from Apple continue to heat up. The latest proof comes from a series of trademark applications for ‘iWatch’, many of which have been directly linked to Apple.
