First responder tech has been due for an upgrade since, well, forever. While we've been busy inventing apps to deliver gourmet meals to our doorsteps, firefighters and paramedics have been stuck with clunky walkie-talkies that belong in a museum. Enter R Plus, the communication device concept that aims to drag emergency services into the modern era.

Imagine you're a firefighter in the middle of a raging inferno. Your radio's swinging wildly somewhere near your hip, and you need backup yesterday. Somya Chowdhary's R Plus concept sidesteps this whole mess by positioning itself right by your mouth. It's like having a built-in megaphone that doesn't mind a little heat. A subtle neck movement or a shoulder shift, and you're set up to send important signals.
