The p-type perovskite oxides La1-x Srx CoO3 are a promising group of complex oxide thermoelectric materials because of its higher Seebeck coefficient. In this paper, the La0.95 Sr0.05 CoO3 thin film was prepared by spin coating. A custom-made micro-electromechanical system based device was used to measure the voltage output and Seebeck coefficient of the thin film. The measured Seebeck coefficient of the thin film was 350 μV/K.
