Skill: Engineering Interest: Health Submission Dates: 12 a.m. ET, Dec 10, 2016 - 11:59 p.m. ET, May 15, 2017 Judging Dates: May 16, 2017 - Jul 26, 2017 Winners Announced: Aug 01, 2017

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!

Judging Criteria

Accuracy, reliability, and frequency of blood alcohol levels as validated by NIAAA.

Functionality, accuracy, and integration of data collection, data transmission and data storage

Safeguards for data integrity and privacy protection for the wearer

Plans for process of manufacture

Marketability and likelihood of bringing the product to market

Appeal and acceptability to wearers
