The Consumer Electronics Show 2017 (CES) in Las Vegas has seen a display of new and amazing technology. Among those, one of the products that might have some real day-to-day usage is a new band from BACtrack, a company known for its breathalyzers that estimate blood alcohol content. The band can be either integrated with an Apple Watch or used independently. 

The band, called the BACtrack Skyn, can measure the wearer’s blood alcohol content in real time. If the user is about to reach a legally drunk state, the device will send out an alert to his/her phone without the user making any effort.

While the band can be used independently of the Apple Watch, you will still need an iPhone to view graphs illustrating your alcohol limit and the BAC content that monitors your alcohol content.

The BACtrack Skyn comes embedded with sensors that can detect small amounts of alcohol released by the wearer’s skin. It then converts the measurements to BAC data using a proprietary algorithm.

The band is priced around $99 and is expected to be released by the end of the year.
