Over the limit? Just ask your headphones!
IF you are worried you may have had a few too many glasses of wine, there’s a new way to find out if it’s safe to drive home – all thanks to your ears. Japanese researchers have come up with a simpler alternative to the breathalyser with a pair of adapted headphones. The device, which was invented by Tokyo Medical and Dental University, picks up chemicals created by alcohol in the blood that waft out of the skin in someone’s ear. A sensor then glows at a different intensity based on how much alcohol remains in the body. The headphones were tested on three men who were asked to drink for five minutes and then monitored over two hours. The findings, published in the journal Scientific Reports, showed that although the peak alcohol reading comes 13 minutes slower than a breath test, it can be read continuously without having to repeatedly breathe into a device.
