초록

The dissolved oxygen sensors with thick film type were fabricated for low cost products and the electrical properties were investigated in the different operating temperatures. Pt paste was used for working electrode and Ag/AgCl paste for reference electrode. The fabricated devices have fast response of current changes according to dissolved oxygen concentrations in the applied voltage of $0.6{\sim}0.8V$. This is expected to apply a chip and/or disposal dissolved oxygen sensors.
