Nanoporous Metal Oxide Film Sensor
PhyMetrix has developed a nanopore geometry with capillary action towards water molecules. This unique structure creates equilibrium between the inside and outside of these pores such that the concentration of water molecules inside the pores is exponentially proportional to the concentration of water molecules outside the pores. Thus the capacitance change due to a small change in water molecule content in the gas is significant enough to produce a repeatable measurement. The following graph depicts the sensor response to partial water vapor pressure of approximately 17 (nF) per decade of partial water vapor pressure (mB).
