JAKE SALTZMAN, NEWS EDITOR [email protected]Researchers at Laval University are developing an optical breathalyzer that can be integrated into the screen of a mobile device. This technology could provide an accessible, inexpensive way to check blood alcohol content (BAC) and reduce alcohol-related accidents and deaths. The technology works by measuring the evaporation rate of the fog that is produced when the user breathes on the phone screen. Since alcohol evaporates faster than water, the higher the alcohol content in the breath, the quicker the evaporation rate. The researchers used components that are already built into...Read full articleRelated content from Photonics MediaArticlesFemtosecond Fiber Laser Ushers in New Class of Visible SourcesResearchers from Laval University reported the development of the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum.
