EpiWear is still very young, to the point where it’s made of 3D-printed parts. The students plan to refine it, however, including a smaller, more refined look that would be more acceptable on a night out.

Should it become a practical reality, you might not have to feel awkward about carrying a life-saving injection with you — and you’d never have to worry about leaving it behind.
