Modern breathalyzers work on a clever electrochemical principle. The subject's breath is passed over a platinum electrode, which causes the alcohol to bind with oxygen, forming acetic acid.

The higher the concentration of alcohol in the breath, the greater the electrical current, which can be read by a simple meter to indicate intoxication levels.
