Wearable Alcohol Biosensor

A Wearable Alcohol Biosensor - A Second Challenge

National Institutes of Health

Total Cash Prizes Offered: $100,000
Type of Challenge: Scientific
Submission Start: 12/10/2016 12:00 AM ET
Submission End: 05/15/2017 11:59 PM ET


The purpose of this Challenge — “A Wearable Alcohol Biosensor: A Second Challenge” — is to produce a prototype of a sleek, unobtrusive wearable capable of monitoring blood alcohol, non-invasively, and in real time. Such a device would significantly advance current alcohol monitoring capabilities. Highest priority will be given to devices that use non-invasive technologies to measure alcohol concentration in the blood or interstitial fluids, as opposed to detection of alcohol exuded through the skin in sweat or vapor. We welcome creative approaches — surprise us!


1st Prize: $200,000.00

2nd Prize: $100,000.00
