dc.description.abstractCharacterization of oxygen sensing properties of Dy Ba2 Cu3 O7-8 (Dy123) sensor utilizing hot spot phenomenon has been conducted. The minimum electric field for the hot spot appearance is 1.5 V/cm. After the hot spot appearance, the output current strongly depended on oxygen partial pressure (PO2) at any selected voltage. The sensor showed very good stability and reproducibility of output current with the response time about 5s. The changing rate of output current increases when P02 decreases , with a maximum average value of 0.039 A/kPa at P02 between 2.5-5 kPa. The sensor is suggested as a potential candidate for low-level oxygen detectionen_US
