Electronic armpit device uses plasma to make deodorant obsolete | A new device is claimed to prevent the stink without the use of deodorant, by killing those bacteria with plasma.
It's not your underarm sweat that stinks, it's the volatile organic compounds (VOCs) produced by bacteria as they break down the fatty acids in that sweat. A new device is claimed to prevent the stink without the use of deodorant, by killing those bacteria with plasma.
Known as the PlaDeo (as in, plasma deodorant), the gadget was invented by doctors TaeHo Lim and JungChi Seo at South Korea's Hanyang University. Pressing and holding the power button causes the PlaDeo to start producing ionized gas (namely cold atmospheric plasma) for 1.5 minutes. These kill odor-causing bacteria like Staphylococcus hominis and Corynebacterium xerosis, mainly by rupturing their outer cell walls.
