“…As pointed out by Dauchot and Van Cakenberghe, there is the possibility of an oscillatory reaction as the diffusion zone in the vicinity of the surface is depleted of reductant by a high reaction rate at the surface. 67 Under appropriate conditions, the surface reaction rate will decrease in a nonlinear fashion as the surface concentration of the adsorbed gas species increases. As a result, the depletion length, which is related to the reaction rate at the surface, may vary from a value that is much smaller than the diffusion length to a value that is much larger.…”

In the past two decades, there has been growing interest in new types of chemically sensitive devices based on the photolithographic batch processing employed by the semiconductor industry. This article reviews several classes of chemical sensors including electrochemical devices based on potentiometry and amperometry, chemical sensors based on thermal processes, and acoustic wave devices. Devices based on dielectric property variation, the core of spectroscopy, are not treated here since many reviews of these topics are available. The article touches on the device principles and reviews some of the more recent developments in each class.
