As we read on Samsung’s latest battery prototypes could lead not only to more powerful wearables, but also to unusual ones.

The batteries found in consumer electronics are pretty solid and inflexible. While there has been some work done in creating liquid batteries, for the most part you won’t find them in your smartphone or smartwatch anytime soon. However Samsung might have something close as far as flexible batteries are concerned. The company has recently taken the wraps off two battery prototypes called the Stripe and the Band.

The first model called Band is meant to be attached to smartwatch straps, as its name implies, to add as much as 50 percent of the device’s original battery life. Stripe, on the other hand, is the thin, bendy strip the model above is holding in her hands and the more versatile between the two. Since it’s extremely thin, with depth measuring 0.3mm, it could be used to create all kinds of wearables, such as smart necklaces and headbands, or even interactive clothing designs. However with these flexible designs, it could lead to interesting designs as far as wearables are concerned in the future.

If these batteries are meant to give rise to different types of wearables, the new lithium-ion batteries the company revealed earlier this year are being developed to make smartphones more reliable. Those ones have the power to extend a typical phone’s battery life to around 21 hours, though it’ll likely take a long time before they’re used with products you can actually buy.

That being said, we should remind you guys that both the Stripe and the Band batteries are currently prototypes. As to when we might see them being mass produced and make their way into future products remains to be seen.
