Water Molecule
H2O
– One Oxygen atom

• Water vapor rapidly transports through the gold layer and equilibrates to the pore walls of the aluminum oxide layer.
• The number of water molecules adsorbed onto the pore walls determines the conductivity of the pore wall.
• Each value of pore wall resistance provides a distinct value of electrical impedance, which in turn is related to the water vapor pressure.
