Abstract
Alcohol concentration in the expiration of a subjective person after drinking was
examined. Beer, Japanese sake, red wine and shochu were adopted as the
alcoholic subjects. The sensor outputs after 1 hour and 2 hours of drinking were
adopted in the technique. The concentration grade was indicated using three
metal-oxide odor sensors. It became obvious that the alcoholic component in the
expiration could remain over 3 hours after drinking. Japanese elderly people
mostly prefer beer and sake according to a questionnaire survey which was
carried out for the aged, and the number of people was 68. The survey was
carried out by a mail correspondence method. The number of males was 37 and
the female number was 31. Many persons who received the questionnaire
preferred beer and sake to whiskey and wine. In this study, the sensor-output
characteristic as a function of passage of time after drinking sake was
investigated and the suitable amount could be indicated by a developed
technique. This means an amount of alcohol from which the subject feels
refreshment of mind and body. In the questionnaire, it became obvious that 61%
of aged men habitually drunk and 18% of females drunk. Women also preferred
wine, plum liquor and shochu cocktails. This system was developed to survey
the aged life style and identify whether they drunk moderately or not. And it can
be also applicable to health monitoring for the elderly person.
Keywords: odor sensor, gas sensor, sensory system, welfare, the aged.
