polymer with gas absorption properties. Any absorption of gas by the polymer will increase the mass of the system, and therefore, lower the frequency of its resonance. Utilizing polymers with gas specific qualities, it is possible tocalibrate the MEMS resonator for gas detection purposes such that the concentrations can bedetermined. The process of absorption is a temperature dependent reaction, therefore control ormonitoring of the device temperature is important.For the gas sensing to be effective, the resonance should be well defined with a high “QualityFactor, Q” at atmospheric pressure. “Quality Factor” is defined as the ratio of the
