Engineering students: Airbrush not just for artists

A microelectrode made in part with an airbrush is seen in this photo shot at a University of Florida laboratory. On a suggestion from a student who had a hobby making paper airplanes, UF engineering students came up with a way to use airbrushes to make the microelectrodes, which are used in glucose monitors for diabetics and other sensors. The airbrush technique is far cheaper and simpler than the standard one, though it works best for small, customized jobs rather than in mass production. Credit: University of Florida
