This Apple Watch band will let you know when you're legally drunk

Fun fact about Vegas: they serve no alcohol there. You can't buy it in stores either. Except that I totally lied. Booze can be bought 24/7 in the City of Sin, which makes it a place appropriate for announcing a product like this one.
At CES 2017, BACtrack – a company known for its breathalyzers – is demoing an Apple Watch band that can measure the wearer's blood alcohol content. Called the BACtrack Skyn, it takes measurements in near-real time, with zero effort required on the user's side. If a legally drunk state is about to be reached, the gizmo sends an alert, letting the user know that they should slow down their intake.
Don't have an Apple Watch? Well, that's okay. The BACtrack Skyn can be used on its own, although you'd still need an iPhone to view the pretty graphs showing your BAC content changing over time.
How does it work? With the right set of sensors, of course. The BACtrack Skyn detects the small amounts of alcohol that is released through the skin. Using a proprietary algorithm, the wearable converts its measurements into a BAC estimate.
The BACtrack Skyn is going to cost about $99 when released later this year, but you can take a look at it if you're attending CES. BYOB, I suppose.

It is really a simple gadget, I would say it probably works as intended. Alcohol is released through sweat after all and the more someone drinks the more they smell of it, taking a reading of the amount in the sweat to tell when you are drunk shouldn't be to hard.

There's too much that can go wrong at the wrist. There's a reason they use an algorithm. They probably did tests with what the watch gave and what the breathalyser gave and used some average results to guess the BAC. I would assume it's acetaldehyde that they test for. The breathalyser tests for this by testing for Methyl compounds in breath. There are other types of methyl compounds in the human body but not a lot of them get to the lungs. If you go on a ketogenic diet where you don't eat any carbs you will be sweating methyl compounds and incorrectly register on the watch. Of course this is if the watch is attempting to work like breathalysers or there's something else it tests for.

Glad to see your article once again, as you've been rare lately.
