Structural and electrical properties of Pt film fabricated by laser scanning and reduction of its oxide film

Abstract A thin platinum (Pt) oxide film was deposited on a polypropylene substrate, and a part of the film was removed and reduced by a laser scanning process using a commercially available apparatus. A Pt film that is electrically isolated from the surroundings was successfully obtained, and the potential of using it as a thermometer was demonstrated by measuring its resistance as a function of temperature in the vicinity of RT. The results indicate that a device structure (thermometer) can be prepared using a Pt oxide film, which is applicable when using a flexible substrate.
