Ever heard of nomophobia? Well, I didn't at first. But it's the fear of your battery getting juiced out with a no charger in sight. So as an after-hours passion project I created a handmade prototype to solve this non-problem: a paper that's printed with a graphene ink which also acts as batteries that's as thin as your sliced cheese.
We then turned these paper batteries into a book sleeve and gave it a nice little design that you'd be proud to carry it. So whenever you've run out of options to resuscitate your forever-dying phone, you could use this little wonder just to keep your nomophobia in check.
