“…This system needs a compact sensor that can monitor NO 2 inside and outside in a rather wide concentration range, from ppb to several ppm levels. Thus far, several solidstate NO 2 sensors, such as resistive [1][2][3][4][5][6], potentiometric [7][8][9], amperometric [10][11][12][13], capacitive [14,15], optic [16,17], and surface acoustic wave (SAW) types [18] have been developed. In particular, resistive-type NO 2 sensors based on oxide-semiconductors are well-suited for the above applications due to their superior properties and simple structure, and as such they have been intensively studied for about 20 years [1][2][3][4][5][6].…”

“…There are a few examples where the sensor response to NO and NO 2 are in the same direction. An electrochemical sensor using the reaction of Ba 2þ with NO or NO 2 to form Ba(NO 3 ) 2 provided emf signals that were in the same direction for NO and NO 2 [5]. A resistance-based sensor using Si 3 N 4 also gave sensor output responses to NO and NO 2 in the same direction, though the mechanism of sensing action was not explained [6].…”

“…While NO sensors have been developed using NO þ -conducting electrolytes, including NO þ -exchanged b alumina [183,184] and Ga 11 O 17 [185] (which forms the same crystal structure as b alumina), NO 2 sensors generally require a nitrate (typically NaNO 3 [186][187][188], Ba(NO 3 ) 2 [189], or a mixture of the two [83,94]) as the auxiliary phase. The outputs of some NO 2 sensors are shown in Figure 13.15 [83,94,[186][187][188][189].…”

“…Zirconia electrolytes have also been used for NO x sensors by using nitrates (NaNO 3 [94] or Ba(NO 3 ) 2 [189]) as auxiliary electrodes. As nitrates are typically less stable than carbonates and sulfates, nonequilibrium-based NO x sensor are more commonly used (these will be discussed later).…”

Solid electrolytes are well suited for use in chemical sensors for high-temperature applications. The first such sensors followed from the use of solid electrolytes for thermodynamic measurements, and are based on galvanic cells, for which the open circuit voltage is related to the concentration of the mobile ionic species, or to another target species through equilibration at the electrode surface. However, sensors can also be based on nonequilibrium, but steady-state, potentials established between electrochemical reactions at the electrode. Another approach is to use the current passing through the electrolyte, rather than the voltage across the electrolyte, as the sensor signal. In this chapter we first describe the different methods for using solid electrolytes in chemical sensors, and then discuss some of the materials challenges and example applications. IntroductionMore than 50 years ago, Kiukkola and Wagner [1] demonstrated that solid electrolytes couldbeusedingalvaniccellstomeasurethethermodynamicpropertiesofoxides.Those pioneering studies subsequently led to the more practical application of solid electrolytes in chemical sensors. The ionic conduction in solid electrolytes is thermally activated and thus its rate increases with increasing temperature; consequently, solid electrolytes are well suited for high-temperature applications. On the other hand, such temperature dependencealsomeansthatsensorsbasedonsolidelectrolytescanrespondsluggishlyor may be inoperable at low temperatures. However, one of the advantages of solid-state devices, such as those based on solid electrolytes, is that they can be miniaturized [2,3].
