N2 - The humidity and salt sensitive characteristics of sensor based on polyimide coated CdS1-xSex semiconductor alloy nanowire chip have been investigated. The composition-graded CdS1-xSex nanowire chip with large size shows excellent photo-sensitivity and stress sensitivity, synthesized by a simple CVD method and its composition can be gradually tuned from CdSe to CdS. The conductivity of the sensor showed good humidity response characteristics with a maximum responsivity (dI / I) of 85% at 80% RH. In addition, the current decreases linearly with increasing salt concentration, indicating that the chip sensor has good salt responsiveness and the best salt responsiveness is 80%. The RH dependent resistance upon illumination exhibits good linearity (R2=0.9948) to guarantee the high prediction accuracy. In addition to good moisture and salt response characteristics, the sensor also exhibits excellent stability and reproducibility.
