Infrared Measurement of Carbon Dioxide in the Human Breath: "Breathe-Through" Devices from Tyndall to the Present Day
The ability to measure carbon dioxide (CO2) in the breath of a patient or capnometry, is one of the fundamental technological advances of modern medicine. I will chronicle the evolution and commercialization of mainstream capnometry based upon infrared measurement of CO2 in the breath using information from the historical record and personal interviews with many of the developers. read

Propane Mosquito Trap
This kind of makes me speechless - leaking gas …ahh I mean fake human breath ? Well, I am really glad it’s cordless. This is the only cordless device that uses CO2 (created by propane to mimic human breath), octenol, and a battery powered thermoelectric module to virtually eradicate mosquitoes over an area up to one [...] read

Steam battery - breath power calculator
[…] how I discovered the "Steam Battery." Essentially, this is an arrangement that produces a voltage across a sample of black ESD (Electro Static Discharge) foam when human breath is applied to one side of it. After I gave my account, I began thinking about well-documented effects that behave similarly to the steam battery. The most prominent is the "hot-point-probe" effect I suggested previously in the "Backscatter" column, in which a p-type or n-type silicon wafer generates a current between […] read
