The Sexy New Intelligent Fragrance

A British design company called PDD is showing off a concept for a wearable fragrance patch that can automatically release more or less perfume depending on what kind of space you're in,
like it'll produce less if you're in a confined space like a car and more if you're in a larger room like a dance club (though we have no idea how it can accurately determine this sort of thing). They're hoping that perfume manufacturers will want to license the Sexy New Intelligent Fragrance, or SNIF, but we're not sure that being able to "optimize" how fragrant you are at all times really offsets the fact that you have to walk around wearing some freaky patch on your arm.
