Syringe 'watch' puts a life-saving allergy shot on your wrist
If you're prone to serious allergic reactions, carrying an epinephrine shot (such as an EpiPen) could be vital. Those shots are often bulky, though, and there's a real chance you could lose yours right before you need it. Students at Rice University have a (relatively) simple solution: put the shot on your wrist. They've developed a wearable, the EpiWear, that hides a foldable epinephrine syringe in a device not much larger than a watch. If you're in an emergency, you just need to unfold it, flick a safety lever and push a button when you're ready to inject the medicine into your thigh.
