• A WO_3-impregnated thin polymer across two closely spaced microelectrodes is employed as a solid-state CO_2 microsensor at 1 atm and room temperature. Its function is based on the WO_3 transformation to the conducting H_xWO_3 by intercalation of released protons from CO_2 equilibration in the polymer. The response to CO_2 concentrations is reversible and linear between 〜0-16% at 〜840 kΩ per 1% change over prolonged operations of 〜80- second switching time. A dependence on residual water in the polymer is detected but exerts no influence on the CO_2 response as long as the polymer is not entirely dried out by H_2O-free gas.
