The electrical properties related to the hydration of the hydrotalcite‐type lamellar compound Zn2Al(OH)6Cl.nH2O are such as to permit the realisation of a humidity sensor. The sensor is achieved by depositing thick film by the screen‐printing technique. First, the means of forming the material is optimised. Two types of sensor are then realised, one working with direct current, the other with alternating current. The performance of each device is studied by means of specified experiments. The authors create a new measurement cell for calibrating the alternating current sensor. Response time measurements are carried out, and results are interpreted and compared.
