Abstract
Cantilever chemical vapor sensors that can be tailored to respond preferentially in frequency by controlling the location of deposition of an adsorbing layer. Cantilever chemical vapor sensor having a base, one or more legs and a tip are fabricated using a gold layer to promote deposition of a sorbing layer of a polymeric material in a desired location, and using a chromium layer to inhibit deposition of the sorbing layer in other locations. Sorbing layers having different glass temperatures Tg and their effects are described. The methods of making such cantilever chemical vapor sensors are described.
