Calibration Study of a Blood Alcohol Level Smart Watch

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03574181
Recruitment Status : Terminated (Extensive changes to the watch design would be needed to produce a robust device.)

Brief Summary:
This trial is designed to test the accuracy of a wristwatch blood alcohol level monitor relative to alcohol breath testing. An established human laboratory self-administration procedure will be followed. Each subject will complete 2 clinic visits over a period of up to 21 days of participation. Study participation is comprised of a baseline assessment to determine eligibility and an alcohol self-administration trial to test the accuracy of the wrist watch blood alcohol level. Subjects will be recruited in two phases of 9 subjects each. The first phase will be conducted to validate a prototype of the wrist watch. The second phase will be conducted to validate a pre-production consumer model of the blood alcohol wrist watch.

Detailed Description:

In this proposed study, the objective is to further demonstrate the reliability of this printed electrochemical gas sensor in the form of a wearable device. This demonstration of reliability among human subjects is an essential part of product development. The monitor will be in a wristband or watch form, similar to a smart watch. This device will be modern, attractive and comfortable. It will also have smart watch features including measuring key physiological parameters (e.g., pulse) and eventually will have connectivity to apps on smart phones and other devices. The aim of the work is to provide a new, noninvasive transdermal alcohol monitor into the market. The transdermal alcohol monitoring market has few wearable products available and innovation has been lacking in this field. This new product will take advantage of current trends in wearable technology. As the public becomes more comfortable with wearable sensors, the blood alcohol monitor will become popular with people interested in health and fitness who want to track their alcohol intake. The product will provide a new, highly reliable and sensitive method for tracking blood alcohol level. This may be particularly beneficial to individuals who seek to reduce the risk of alcohol use by limiting peak blood alcohol level. If successful, this technology could be adopted in many areas including clinical and medical treatment, employee wellness programs, alcohol clinical trials, and as part of brief interventions that target at-risk drinkers.

The specific objective of this study is to determine whether the printed electrochemical gas sensor designed to measure blood alcohol level will be sensitive and reliable when compared to a standard measure of blood alcohol level taken by a breathalyzer. If this sensor proves sensitive to changes in blood alcohol level and can reliably measure blood alcohol level relative to a "gold standard" method, there are significant opportunities to use this technology in consumer health applications and clinical research.
