A team of Italian researchers are hoping to make catching drunk drivers easier and less expensive for police officers by developing a new portable breathalyzer capable of testing for precise alcohol concentrations.
Their research, which appears in Tuesday’s edition of The Optical Society’s (OSA) journal Optical Materials Express, describes a new portable device that would change colors from green to red when it detected higher levels of alcohol. Unlike the color-changing devices currently available, however, this unit would reportedly be reusable and would provide an exact digital readout.
