Proof-of-concept thermoelectric oxygen sensor exploiting oxygen mobility of GdBaCo2O5+δ

Soumya Biswas, Madhujith M K, Vinayak Kamble

In this paper, we demonstrate a proof-of-concept oxygen sensor based on the thermoelectric principle using polycrystalline $GdBaC{o}_2{O}_{5+\delta }$ where 0.45<$\delta$<0.55 (GDCO). The lattice…
