Temporary Tattoo May Help in Tracking Alcohol Levels


Alcohol levels in human body can be tracked using a temporary tattoo, according to a report published on April 12, 2018.

This new wearable device was developed by engineers at the University of California, San Diego. The alcohol levels will be transferred to a connected mobile phone and then, the alcohol intake is measured by the device. This wearable device was very much similar to a temporary tattoo that sits directly on the skin. It works by stimulating perspiration and later, the alcohol level in a person’s body is measured using this.

Seila Selimovic, director of the program said, “It resembles a temporary tattoo, but is actually a biosensor patch that is embedded with several flexible wireless components.” One of the components of the device stimulate perspiration on the skin below the patch and difference in the electric current flowing through the perspiration is sensed by another component. Alcohol level is measured with the help of these electric signals and is sent to the user’s mobile phone.

A major advantage of this device is that the measurement takes only few minutes. Patrick Mercier, one of the senior authors of the article said, “Measuring alcohol in sweat has been attempted before, but those technologies took 2-3 hours to measure alcohol levels.” The newly developed device takes 8 minutes to send alcohol levels to the user’s cell phone.

The efforts to create wearables and at-home breathalyzers that effectively measure alcohol levels have been mixed. The device works quickly and almost accurately, which predicts the future of the product. This new development is expected to increase growth of medical sensors market, as elaborated in the medical sensors market report published by Coherent Market Insights.
