This work addresses a simplified manufacturing method and sensing properties of the porous layer type. Yttria stabilized zirconia (YSZ) and YSZ/cordierite composite sheets are used as solid electrolyte and as diffusion barrier, respectively, for the porous layer type sensor. Using a lamination process, the sensors are fabricated as a monolithic body containing patterned heater. Experimental results revealed that the porous layer type sensor with YSZ/5 wt% cordierite diffusion layer is most effective for the limiting current plateau having a wide voltage regime. The porous layer type sensor showed a faster response time and a broad voltage regime having a low limiting current output probably due to the smaller area of the diffusion layer. ？ 2006 IEEE.
