Metal oxide gas sensors extend their range

An impedance measurement technique that is based on dielectric excitation at specific frequencies can improve the performance of semiconducting metal oxide gas sensors, providing a linear sensing signal over a wide range of gas concentrations. The cover shows a photograph of an integrated circuit impedance analyser (front) and three gas-sensing chips that can be used in the measurements.
