Introducing BACtrack Skyn, Winner of the National Institute of Health's "Wearable Alcohol Biosensor Challenge"

BACtrack's innovative prototype won the first place prize of $200,000

The Challenge


In the search of a wearable device capable of measuring blood alcohol levels in real time, the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institute of Health, issued the Wearable Alcohol Biosensor Challenge in March of 2015.

The goal of the challenge was to create a device that not only improved on existing technology by providing real-time BAC monitoring, but also came with an inconspicuous design that is appealing to the general public. The challenge stated that the device must be able to measure blood alcohol level, interpret and store the data, or transmit it to a smartphone or other device by wireless transmission.

What is BACtrack Skyn?

BACtrack Skyn is a low cost, wearable, non-invasive alcohol monitoring device that sends Transdermal Alcohol Content (TAC) results via Bluetooth to an iOS device. With BACtrack's proprietary algorithm, TAC results are then converted to an estimate of a user's historical BAC.

Samples can be taken as frequently as every second, can be sent from the wrist device to a smartphone, and if desired, to a cloud server for further distribution.

What Can BACtrack Skyn Do?

With BACtrack Skyn, you can passively track alcohol consumption in real-time. There’s no need to take a breath alcohol test – your estimated BAC result is just there on your wrist, continuously!

By syncing with an app on a smartphone or smartwatch, you can get powerful and actionable data. For instance, your phone could vibrate to notify you that you're approaching 0.04 %BAC and remind you to slow down your drinking, or in the case of sobriety monitoring, a family member could receive a notification when your BAC has gone above 0.00 %BAC.

How It Works

BACtrack Skyn uses transdermal monitoring (via an electrochemical sensor) to track the ethanol molecules escaping through your skin. While most consumed alcohol is processed within the body, some escapes through the skin in the form of ethanol. As a result, we're able to read this ethanol signal, and use our proprietary algorithm and device calibration to convert the raw response reading to an estimated Blood Alcohol Content (BAC) reading.
