Abstract


In this paper, a new process for the preparation of gas sensors using printing technology . The process has the low-temperature , low-cost production process is relatively simple and fully compatible with silicon COMS technology features. The paper also raises the gas sensor and integrated circuit chip integrated wireless sensor system design framework . The main research content and results : 1 . Polyaniline and polypyrrole the ammonia sensitive \Study the DC characteristics of the sensor response to ammonia , the ammonia concentration and AC impedance . About 150Hz-2kHz AC impedance nearly an order of magnitude higher than the DC impedance of the sensor sensitivity is greatly increased . Studied the influence of the proportion of acid-doped polyaniline and polypyrrole , the sensitivity of the ammonia sensor . When the proportion of acid-doped polyaniline and polyaniline found doped acid decline in the proportion between the 0.1-1.5 range , the amount of change of the AC impedance is constantly increasing . 4 conductive polymer polyaniline and polypyrrole materials sensitive selectivity of the gas , the material on the air and water vapor substantially no response . The results show that under certain conditions with the actual application prospects ammonia sensor based on polyaniline and polypyrrole . 5 Construction of an AC impedance fitting model based on polyaniline and polypyrrole ammonia sensor AC impedance change process explained .
