Wearable Breathalyser

Wellington’s Matt Leggett has invented a breathalyser jacket which lets the wearer know whether they’ve had too much to drive, with results displayed on lights stitched into the forearm of the jacket; the more the glow, the more alcohol is being detected. Leggett explains: “The lights will only glow for a period of around a minute after the breath sample has been taken, enough time for wearer to process the information without becoming a walking light show. To the unfamiliar observer, the jackets function is a mystery. The main aim of the breathalyser jacket is to provide the wearer with enough information regarding the amount alcohol on his/her breath to make a decision on whether driving is in fact a good idea.”
