Tencent Digital (Compile: Guti) Each year, only 14% of accidents caused by accidents in the UK are due to drunk driving. Alcohol can reduce people's ability to discern things at a distance, prolong reaction time, and cause people to lose their visual reaction. It is very easy to cause traffic accidents.
Therefore, in order to avoid allowing more people to drink and drink, engineers at the National Institute of Biomedical Imaging and Bioengineering have developed a new alcohol detection device. Yes, this device looks like a tattoo. It can analyze the alcohol content in the sweat from our body.
"This is a temporary tattoo that stimulates the body to excrete sweat and then analyzes what is inside the body through built-in biosensors and wireless components," said project member Seila Selimovic. "One of the components emits chemicals to stimulate the skin to sweat, and the other component uses sensory changes to analyze the sweat that is secreted by humans. Finally, it analyzes the amount of sweat and sends the results to the user's smartphone." in."
The electronic tattoo is small and non-invasive and invisible. Researchers say it can be used to monitor people who often drink and want to drink after driving. From the actual results, the effect of this electronic tattoo is more obvious than the effect of other similar products.
"The average device uses alcohol to analyze the alcohol content, which takes about 2 to 3 hours, and this speed is basically very slow," Patrick Mercier said. "And our technology can detect results in 8 minutes and then send it to a smartphone, so real-time monitoring of the content becomes a possibility."
It is reported that the detailed results of this study have been published in the Journal ACS Sensors magazine.
