摘要
In this work various capacitive transduction schemes have been evaluated by performing numerical solution using COMSOL Multiphysics. Seven different schemes were evaluated by keeping the printed sensor finger widths up to 200 mu m and the same interspacing between these electrodes. The geometrical structure of transduction electrodes of the sensor directly relates to the sensitivity of the sensor and its performance. Our findings suggest that customized triangular arrow electrode configuration provides high transduction signals and is suitable for many gas sensing applications and environmental sensors.
