CES 2017: New wristband can tell you how drunk you are


Have you ever wondered how drunk you are?

Well a new wearable developed by Californian company Milo Sensors has developed a wristband known as Proof that tells you how much alcohol is in your system.

Proof reads alcohol molecules through your skin with its built in electrochemical sensor able to convert alcohol into an electrical current in order to help display accurate alcohol levels in your blood.

If its accompanying smartphone app then says that your alcohol levels are too high, Proof can predict when you will be safe to drive and even send you an alert when you have reached this level.

Proof, which was unveiled at the Consumer Electronics Show (CES 2107) in Las Vegas earlier this week, also has a feature that allows users to track family or friends if they are out for the night, and make sure they are drinking responsibly.

Evan Strenk the CEO of Milo Sensors hopes that the app will change the way people drink and “empower people to make educated decision about alcohol.”

The wristband is expected to go on sale later this year and retail at around THB5,000.

It will be marketed as “a premium wearable for happy hours, wine tastings, and more,” the device uses disposable cartridges to give “reliable alcohol tracking over 12 hours.”

Strenk went on to explain that: “Milo’s wrist-worn biometric sensor was developed to provide an accurate and affordable means for continuously tracking blood alcohol level without needing to blow into a breathalyser or take a blood test.”

Co-founder Bob Lansdorp told WearableZone: “The alcohol that’s in your bloodstream diffuses through your skin, and we pick up those trace amounts that would naturally just go off into the air. 

“We capture those and turn them into a signal that relates to the alcohol content in your blood.”

“With our device, you put it on at the beginning of the night, forget about it, and throughout the night it tracks your BAL continuously,” he added.
