Abstract:
... We report a light, flexible, and low-power poly(ionic liquid)/alumina composite CO₂ sensor. We monitor the direct-current resistance changes as a function of CO₂ concentration and relative humidity and demonstrate fast and reversible sensing kinetics. Moreover, on the basis of the alternating-current impedance measurements we propose a sensing mechanism related to proton conduction and gas diffusi ...
