A Wristband That Can Tell You If You're Too Drunk To Drive

[Muzaffar]

No one should ever drive drunk, but it can be difficult to monitor your blood alcohol content levels without taking a breathalyzer test. While there are some small breathalyzers ar on the market, they can be clumsy and awkward to use in public. Proof is a unique and elegant solution to this problem, as it's a wearable wristband that can discretely analyze you BAC levels through your skin. The makers of Proof managed to earn nearly twice what they were asking for after launching a successful crowdfunding campaign. The wristband is set to begin shipping at full production capacity in late 2017.
