The Proof bracelet connects to a user’s phone
A wearable device is hoping to track how much alcohol is in a person’s system.
The Proof wristband connects to a user’s phone and sends alerts when their blood alcohol level is high.
The wristband has LED lighting and vibration alerts.
It also allows users to set pre-selected Blood Alcohol Concentration (BAC) levels.
A disposable cartridge system in the wristband measures alcohol levels through perspiration.
While a rechargeable battery in the device will last for up to four days, the manufacturer says.
One cartridge will provide over 12 hours of alcohol tracking.
The band is set to be released in the US later this year – with an estimated cost of between US$100 and US$150 (€94 and €141).
The company behind the wristband reportedly plans to launch a crowdfunding campaign.
The device was showcased at CES 2017 in Las Vegas - the world's biggest tech show.
