5.5.6 Stacked Type Potentiometric Solid-State CO2 Gas Sensor for Miniaturization

N-.J. Choi, H-.K. Lee, S. E. Moon, W. S. Yang & J. Kim
A stacked type photentiometric solid-state (S-PSS) carbon dioxide (CO2) sensor based on Li ion was designed and fabricated on alumina substrate by mass production techniques. This design can reduce the 70 % of active area because no reference material is required. All materials were screen-printed except for electrolyte which was deposited thermal evaporation. The prepared materials were characterized by X-ray diffraction analysis and scanning electron microscopy. Gas response characteristics of S-PSS and planar type PSS...
