Aterica Digital Health, based in Waterloo, Canada, has designed an EpiPen case that's difficult to lose or leave behind.The "Veta smart case" uses sensors, Bluetooth radios and other technology to broadcast its location and perform several other tricks that could help users survive anaphylaxis. The case itself works with an app that runs on either Apple iOS or Google Android. Whenever a user's smartphone and case get too far apart to communicate, an alert appears on the phone. If a user misplaces a case, the app can reveal its exact location by tracking the signal it emits.
