使用氧化钇稳定氧化锆（YSZ）与金属氧化物传感电极（SE）和锰基参比电极（RE）耦合，制造了小型化混合电位型平面传感器。在所检查的不同氧化物-SE中，发现使用Cr 2 O 3-SE的传感器在550℃和潮湿工作条件（5体积％水蒸气）下对碳氢化合物（HC）具有相对较高的选择性，对饱和和不饱和HC表现出相似的灵敏度值。通过向Cr 2 O 3-SE 中添加30 wt% NiCr 2 O 4 ，HCs 敏感性得到增强。所开发的传感器的灵敏度与 HC 浓度的对数呈线性相关。
Miniaturized mixed-potential-type planar-like sensors using yttria-stabilized zirconia (YSZ) coupled with a metal oxide sensing electrode (SE) and a Mn-based reference electrode (RE) were fabricated. Among the different oxide-SEs examined, the sensor using Cr 2 O 3-SE was found to give comparatively high selectivity towards hydrocarbons (HCs) at 550 C under a humid working condition (5 vol% water vapor), exhibiting similar values of sensitivity to both saturated and unsaturated HCs. By the addition of 30 wt% NiCr 2 O 4 into the Cr 2 O 3-SE, HCs sensitivity was augmented. The sensitivity of the developed sensor had a linear dependence on the logarithm of HC concentration.
