One of my biggest gripes with today’s smartwatches is charging — specifically, that I have to plug in my wristputer every night, or it becomes a useless and expensive hunk of metal. But if this flexible solar-powered battery becomes a reality, we could finally have wearables that live up to the hype.
A team from the University of Illinois, Northwest University, South Korea and China developed the battery, which they say is capable of changing its shape to fit in various devices. The various components of the battery and solar cells are integrated into a silicone shell and connected by flexible copper-polymer joints. The result is a charging and storage solution that can stretch and bend by 30 percent without losing its ability to generate solar charge.
