New electrochemical and physical measurements on sensitive glasses in thin-film technology

Abstract

All-solid-state sensors have several advantages compared to conventional ones. These include, e.g., miniaturization, planar design, location independence and an uncom­plicated realization of sensors for high pressure and high temperature. Therefore, a number of physical sensors, such as temperature sensors, pressure sensors, rotation angle sensors and force sensors are available in thin-film techniques. The presented paper shows the advantages to combination of thin and thick film tech­niques to manufacture electrochemical sensors, especially using pulsed laser ablation to create amorphous layers of glass. Furthermore, it investigates the range of possibilities for characterization of bulk and surface properties with electrochemical methods and specialized techniques with thermally stimulated currents (TSC).
