Abstract

We propose a CO2 gas sensor based on an impedance change of ionic gel (IG) according to the CO2 gas concentration. The sensor consists of an IG film patterned on electrodes. The impedance of the IG changes when the IG absorbs CO2 gas. CO2 gas concentration can be detected by measuring the amount of impedance change. Our proposal sensor has a merit that power consumption is very low (<1μW). It is because ionic liquid (IL) and IG have selective gas solubility and high impedance. The high impedance means that large current is not required for the measurement.
