A lot of our devices are getting smaller and thinner these days, and as such, there needs to be new ways of keeping them powered. Thanks to the work of researchers at the Chemnitz University of Technology, they might have figured out a way to do that by developing batteries the size of a grain of salt.
Due to its incredibly small size, its use has far greater potential where it might be able to power biocompatible sensor systems placed in the human body. Now, these types of tiny batteries aren’t exactly new. There have been other similar developments in the past, but unlike some of its predecessors, this battery is actually powerful enough to power larger devices like computers.
The researchers claim that the design of their battery was inspired by the Swiss roll, where layers of the battery can be rolled up without taking up too much space, compared to more traditional batteries we see in smartphones and laptops where they are long and flat, and the larger the capacity, the bigger the footprint.
That being said, before we get too excited about these microbatteries, we’ve yet to see any real world application of this invention so it could be a while before its design and benefits can be seen or felt.
