CPR saves lives, but incorrectly administered CPR does quite the opposite. We can use all the help we can get in the proper CPR department, which is why this CPR glove is awesome. That and the fact that it looks pretty sweet and makes us feel like it's the future.

The glove can sense a heartrate no matter how faint, displaying it to the wearer. It also has sensors and microchips that can measure the frequency and depth of your compressions, making sure you're doing it properly. I, for one, would feel better having someone wearing this going to work on my poor, fragile chest than someone who had no idea what they were doing and just started beating on my ribcage. But hey, here's hoping I don't need either anytime soon. — Adam Frucci
