A short review of gas sensors based on interdigital electrode

In the seek of getting better sensibility, selectivity, times of response and recovery, interdigital electrode structures have been increasingly used in nano and microelectronic devices designed to the gas sensing, in the last decades, given their importance and performance characteristics presented for each new usage. In this sense, this work not only addresses on a review of performed researches along the years, but also discusses recent developments of gas sensors based on interdigital electrodes.
