Among various metal oxides, titanium dioxide (TiO2) has received considerable interest as a gas-sensing material owing to its high reliability at high operating temperatures. Nonetheless, TiO2 generally has low sensitivity to target gases. In particu

Typical BTEX sensors that exhibit different response for individual BTEX were difficult to accurately measure the amount of mixed BTEX with an arbitrary ratio and thus a calibration was required for accurate concentration measurement. Herein we demon

This paper describes an energy-efficient resistor-to-digital converter (RDC) for detecting benzene, toluene, ethylbenzene and xylene (BTEX). The sensor’s selectivity is adjusted by the different heat levels, thereby detecting the BTEX with a single
