Our publication by Kim et al. [7] is not purposed to criticize others but we try to deliver the problems that the current sensor has. In fact, I think that we have studied all types of sensor structure for Al melt since 2002 and experienced many prob

Solid-state bi-electrolyte carbon dioxide sensors with an yttira stabilized zirconia (YSZ) and sodium beta alumina (NBA) heterojunction were fabricated using the tape casting method to measure CO 2 concentrations in the air. The enhanced interface be

The potential for using superposition to predict the response of resistive-type gas sensors when they are exposed to more than a single gas was tested using two SnO 2 -based sensors. It is proposed that the selectivity of resistive-type gas sensors c

Solid state electrochemical and chemo-resistive gas sensors have been used widely but can operate only under high temperature. For reducing the power consumption and optimizing the structure of the substrate of these sensors, we conducted device and
