Other tech: artificial gill closer

Artificial Gills: One Big Stroke Closer To Reality The key to artificial gills, explains Harihara Baskaran, an engineer at Case Western Reserve University, is getting water to flow easily through microchannels, which mimic a real gill. Working with Infoscitex of Waltham, Mass., Baskaran is using chipmaking techniques to create tiny devices with hundreds of channels. Bump that up to 250,000 channels, and the device could generate enough oxygen for a person. More on Harihara Baskaran’s work
