The folks who came up with the self-healing iPhone case is now back with something a lot more impressive. Innerexile's earlier technology could repair light scratches within about half a minute (given the right temperature, that is), but the latest version can do the same within just a second! Seriously, you'd have to study very hard to witness that brief magical moment, which proved to be tricky in our brass brush test video after the break. So what's the secret sauce behind this new coating? Well, it's dotted with microcapsules that contain an adhesive-like liquid, and when damaged, the liquid will fill the void so quickly that you probably won't even realize you've just scratched your case or screen protector.
