Tokyo Medical University experts have invented headphones to measure blood alcohol levels. A description of the development has been published in the journal Scientific Reports.
The device is able to collect real-time data from ethanol vapors, which are released by the skin of the ears. The device consists of a special chamber to collect the gas surrounding the ear and a biochemical sensor. When traces of alcohol are detected in the body, a light indicator lights up, the brightness of which tells you the concentration of alcohol.
According to the scientists, this method of information collection is more reliable than the measurement of alcohol concentration in the air a person exhales. At the same time, this device can be used for other purposes. For example, to diagnose various diseases and assess the body’s metabolism.
Earlier psychiatrist-drug therapist Alexander Kovtun called the dose of alcohol, which is harmless for the body. According to him, a therapeutic dose of alcohol can be considered a teaspoon taken as a myorelaxant, adaptogen and anti-stress. “Anything more is already toxic and poisonous doses, to a greater or lesser extent it will do harm,” the expert noted.
