- A solid electrolyte potentiometric CO 2 gas sensor has been considered as a candidate for miniaturization into a micro-sensor form. However, the solid electrolyte potentiometric CO 2 gas sensor is composed of three components: a reference, a sensing material, and a solid electrolyte. This study reports the fabrication of a solid electrolyte potentiometric CO 2 gas sensor with a native reference material from the solid electrolyte (Li 3PO 4), which means one component of the sensor can be omitted and the fabrication process can be simplified compared to the process for a conventional solid electrolyte potentiometric CO 2 gas sensor. The sensor containing Li 3PO 4, which acted as the reference material as well as the sensing material, showed a comparable response (75 mV/dec at 500 °C) to CO 2 gas when we compared the sensor with a conventional solid electrolyte CO 2 gas sensor (73 mV/dec at 500 °C) with a coplanar configuration containing Li 2TiO 3 as the reference material and Li 3PO 4 as the solid electrolyte. © 2012 The Korean Physical Society.
