Abstract

Sensing layer mixed perovskite oxide, La_0.1Sr_0.9Co_0.4Fe_0.6O_3-δ (LSCF), and Pd-loaded SnO₂ nanoparticles (LSCF@Pd-SnO₂) was deposited on the membrane of MEMS device by injection method, and its gas sensing properties to reducing gases and VOCs were investigated by heating sensor in pulse mode with heaters in ON and OFF state for one second repeatedly. The MEMS sensor showed fast response, high sensitivity and stability to 200 ppm C₇H₈ at 250°C by pulse heating with extremely low power consumption.
