Earmuffs can measure blood alcohol levels through the skin

Daily Mail - Science & tech

Suspected drink drivers could soon be told to put on a pair of earmuffs by police, if a new device comes to fruition. Japanese scientists have developed a pair of earmuffs that can estimate blood alcohol levels based on'transcutaneous gas' – gas released through the skin. The earmuffs, presented as a proof-of-concept in a new study, detect ethanol compounds in transcutaneous gas released by the ears. In trials, the device measured alcohol intake as well as a traditional breathalyser, although the process took a lot longer – more than two hours, compared with what can be just a few minutes for breathalysers when stopped on the roadside. But a breathalyser test tends to be much more invasive, often requiring a tube to be inserted into the mouth.

Your smartphone could tell if you are drunk by analysing your walk

New Scientist

Smartphones may soon be able to tell whether someone is drunk based on the way they are walking, even if the phone user is unaware of the fact. Brian Suffoletto, now at Stanford University in California, and his colleagues at the University of Pittsburgh in Pennsylvania, wanted to see if they could take advantage of the accelerometers embedded within most smartphones to detect changes in walking patterns that occur when people are drunk. Suffoletto and his team recruited 22 volunteers and gave each an hour to consume a mixed drink with enough vodka to produce a breath alcohol concentration of 0.2 per cent, well above the legal limit for driving in the US of 0.08. They then strapped a smartphone to each participant's lower back. Every hour for the next 7 hours, the volunteers were breathalysed and then asked to walk in a straight line for 10 steps, turn around, and then walk back 10 steps.

Calculating Alcohol Risk in a Visualisation Tool for Promoting Healthy Behaviour

AAAI Conferences

There is an urgent need for interventions to assist teenagers and young adults in appreciating the physical and social risks of binge drinking. While research on the health risks associated with alcohol abuse is well developed, the translation and communication of this knowledge to young people is not. This paper describes a prototype visualisation tool, an Alcohol Risk Calculator, that provides personalised information on risks associated with alcohol consumption based on individual drinking habits. Its design is informed by studies of graphical literacy, evidence on forms of presenting risk that aid understanding, and theory that provides insight into changing health damaging behaviour.

A temporary tattoo may be able to track your alcohol levels


A new monitoring device could help people discreetly measure their alcohol intake by transmitting alcohol levels to a connected cell phone. The tech, developed by engineers at the University of California, San Diego, is a small wearable, comparable to a temporary tattoo, that sits directly on the skin. According to Science Daily, it works by stimulating perspiration, which the device can then use to measure the level of alcohol in the person's system. "It resembles a temporary tattoo, but is actually a biosensor patch that is embedded with several flexible wireless components," Seila Selimovic, the director of the program that helped develop this tech, told Science Daily. "One component releases a chemical that stimulates perspiration on the skin below the patch.

The smart stick-on tattoo that can monitor your alcohol levels

A new smart stick on tattoo will be able to monitor exactly how much a person is drinking. The flexible patch can detect a person's blood-alcohol level from their sweat. The flexible patch can detect a person's blood-alcohol level from their sweat. In the U.S., one person dies every 53 minutes in an alcohol-related car accident, according to the Centers for Disease Control and Prevention. Currently, ignition interlock devices are being marketed as a way to prevent drunk drivers from starting a car engine.
