Electrochemical Sensors for CO/NOx Detection in Automotive ...

Recent progress in the development of a β-alumina gas sensor for automotive applications is reported. The sensing device consists of two solid electrolytes (namely a thin film of sodium sulfate deposited on β-alumina by appropriate treatment in a gaseous atmosphere), with two electrodes having different catalytic properties, one made of platinum, the other of gold. The β-alumina component ...

Signal conditioning for electrochemical sensors

Electrochemical sensors are widely used in the medical sector. For example, to monitor the concentration of glucose in the blood of diabetic patients, a glucometer (glucose meter) is used. In this case, the disposable test strips are the electrochemical sensors. Figure 1 illustrates the carbon monoxide and the glucometer test-strip sensors.

Chapter 2 Electrochemical Sensors

Electrochemical sensors are minimally affected bypressure changes. However, it is important to keep theentire sensor within the same pressure since differen-tial pressure within the sensor can cause sensor dam-age. Electrochemical sensors are also quite sensitiveto temperature and, therefore, the sensors are typi-cally internally temperature-compensated. However,it is better to keep the sample …
