A new technique, based on an optical fiber interferometer, is described for in situ measurement of electrode strain during electrode reactions. A model is presented which relates changes in optical path length of the fibers in the various strain components in the electrode. Measurements of strain associated with electrodeposition of nickel as a function of the thickness of the nickel layer are reported and compared to a simple model. Measurements of strain associated with the anodic oxidation of titanium are also reported. The strain generated in the titanium has a component which is independent of applied potential after oxide growth is complete and a component which is dependent on the applied potential. The potential dependent term is identified as an electrostriction effect in the anodic oxide enhanced by the porous nature of the electrode. The potential independent term comes from compressive stress in the anodic oxide induced by the growth process.
