Summary

A key technology in characterizing chemical and biological processes is the determination of local thin films properties on substrate surface layers that are coated with biochemical active materials. with increasing demands for data logging, the need for cost efficient, simple and reproducible biochemical sensors steadily rises. the optical measurement device presented in this paper is based on the principle of thin film interferometry. Modulating the transparent substrate of the sensor allows us to extend the measurement principle to slowly varying or static biochemical processes. in order to produce cost-efficient transparent substrates with high optical qualities, PLZT 9/65/35 ceramics prepared by electrophoretic deposition have been used and characterized.
