The researchers note that the goal of the device is ultimately to detect halitosis, a.k.a.
Regardless of the claim, this particular detector uses a novel combination of substances to detect hydrogen sulfide.
They then “electrospun” the particles into nanofibers that work in a way such that their electrical conductivity changes when they interact with hydrogen sulfide.
The scientists say their device correctly identified bad breath 86% of the time.
Although, unfortunately, we couldn’t find any prototype illustrations of the device.
