Applied gate voltages affect the channel carrier concentration and surface potential of the metal oxide, thus causing a change in sensitivity. With a gate-voltage-pulse operation a novel measurement t

Both stimuli have been found to induce a sequence of reactions with increasingly longer time constants: short-term changes in gas sensing properties and longer-term changes in the clean-air baseline level.

The Electroadsorptive Effect is invaluable when used in MEMS gas sensors. .The authors use a general approach that covers new insights into temperature modulation and the use of light. The emphasis is given to electrical fields in gas sensors, which c
