Coated optical fibers in an optical interferometer configuration have been used to measure in situ and in real time the strains induced by chemical changes in the coatings. With a palladium coating this technique has been used to measure hydrogen gas concentrations between 10 ppB and 2%. Using a metal coated fiber in an electrochemical cell, the strains induced during electrodeposition of palladium and nickel have been measured. Strains associated with the anodic oxidation of titanium have also been measured. The implications of this new technique for other chemical and electrochemical environments are discussed.
