Milo Sensors has announced a wearable that's capable of monitoring your blood alcohol content by analyzing your perspiration. The "Proof" is a slim band that'll monitor your BAC and send the data to a mobile app for viewing.
Users can set alarms before they begin drinking so that the system notifies them upon hitting 0.08, for example, which is often the legal limit for driving.
There's a breathalyzer out there but no one uses it because they're awkward. The use case there is you put our sensor on, at 6 p.m., you set your alarms for yourself, and everything's paired with an app. [When I check my phone] you don't even know if I'm messaging someone or checking my BAC. And because it's continuous tracing, you can set alarms for yourself, like hitting .08 percent. I want to be alerted, maybe if I'm driving home, and you can connect with safety buddies, friends and family at undesirable levels. - Evan Strenk, founder, Milo Sensors
You have to use replaceable cartridges in the band. Each one costs a few dollars and lasts 12 hours.
The NIH reviewed the device last year and compared it against breathalyzers and blood samples. Milo Sensors ended up receiving a cash prize from the organization.
A release is expected sometime in 2017. The Proof will cost $100 to $150.
