CONTROLLED ZnO DEPOSITS FOR GAS SENSORS
Résumé
Zinc oxide (ZnO) is widely used for its capability to detect gases. There are several known methods to synthetize and deposit ZnO for gas sensor applications. We have developed a new process based on ZnO nanoparticles from Sigma Aldrich manufacturer deposited by an inkjet technique. The process achieved is based on stable ZnO nanoparticles ink obtained by mixing 10% weight of commercial powder with diethylene glycol (DEG). This ink has been deposited on Pamela Yoboué et al. 56 a microhotplate that can operate up to 550°C with a low power of consumption (less than 60mW). The gas tests presented in this article show good results concerning the sensor response and its stability in the presence of gases.
