Abstract
Provided is a capacitive gas sensor. The capacitive gas sensor comprises a sensitive material for adsorbing and desorbing a target gas, an upper electrode surrounding the sensitive material, a lower electrode facing the upper electrode, and a porous structure disposed between the upper electrode and the lower electrode, wherein the capacitance of the sensitive material changes as the sensitive material adsorbs and desorbs the target gas.
