QUARTZ CRYSTAL MICROBALANCE GAS SENSOR WITH INK-JET PRINTED NANODIAMOND SENSITIVE LAYER

Pavel Kulha – Jiří Kroutil – Alexandr Laposa – Václav Procházka – Miroslav Husák

   The paper presents fabrication and characterization of a Quartz Crystal Microbalance based gas sensor with a diamond powder sensitive layer deposited using the ink-jet printing technique. The sensor was exposed to a low concentration of ammonia, acetone vapors and different levels of humidity. Impedance characteristics close to the natural resonant frequency of $10\,$MHz were examined. The sensor exhibits significant shifts in serial resonant frequency under different gas environments.

Keywords: gas sensor, QCM, nanodiamond, ink-jet printing
