A polyelectrolyte as humidity sensing material: influence of the preparation parameters on its sensing property
نویسندگان
چکیده
The kinetic behaviour of humidity sensors based on a cross-linked interpenetrated polyelectrolyte was investigated. Various parameters were changed in order to study their effect on the response to a humidity variation. The influence of the way of preparation of the polymer and of the sensing layer thickness are reported and discussed.

متن کاملImpedance characteristics of thin films humidity sensing elements based on Bi - doped TiO 2
The paper proposes results from the investigations of humidity sensing elements based on Bi-doped TiO 2 thin films, prepared by a sol-gel method. Titanium n-butoxide was used as a starting material for the preparation of the experimental samples, and bismuth acetate as doping compound. The samples were sintered at 400°C. Afterwards, the samples were placed into a calibrated humidity chamber and...
