PROOF: get continuous alcohol measurements through your skin

Wearables represent a convenient method for individuals to monitor their alcohol intake.

Such devices not only have the potential to save lives by cutting back on instances of drunk driving, but also to combat chronic health problems arising from alcoholism. We’ve reported now on a number of gadgets and even a sweat-inducing tattoo that can monitor alcohol levels, but not all of this has materialized and we have yet to see something take off in a really big way.

PROOF is the new kid on the black. Although the wearable resembles a Fitbit or Garmin fitness tracker, you won’t find a step, calorie or distance count. PROOF tracks your BAC levels through your skin, and nothing else.

The device does this thanks to an enzyme-based electrochemical sensor (Enzymatic Electrochemical Sensor), which converts perspired alcohol into BAC levels. It then sends the info in real-time via Bluetooth to the accompanying app.

Your BAC levels are communicated back to you via the multi-colored LEDs on the face of the wearable, and in more detail in the smartphone app. The info is actually more up-to-date compared to breathalyzers, which require wait times of up to 30 minutes after your last drink to avoid false positives.

If you had a few too many, you will even get a time to sober estimate. Furthermore, you can set your own alerts and get notified when you’ve reached your designated levels through vibration and LED lights.

The sensors do need to be changed from time to time to ensure accuracy. Each locks in magnetically on the underside of the wristband, and is good for 1 data point per second over 12 hours of continuous use. The lightweight wearable (20 grams) is made of super-soft silicone, provides secure data encryption and has enough juice to run for 4 days on a full charge.
