FEM Modeling of Sensitive Layer Swelling Effect on Microbalance Gas Sensor Based on TFBAR Resonator

Abstract; The electromechanical response of a chemical gas sensor based on a TFBAR (Thin Film Bulk Acoustic Resonator) structure coated with a sensitive polymer layer was simulated with a FEM (Finite Elements Method) software (COMSOL Multiphysics®). The principle of sensing is based on the change of the mechanical properties of the polymer due to the […]

The heterostructure ZnO/Al/SiO2/Si fabrication for piezoelectric SAW and BAW transducers and sensors

Abstract; Zinc oxide (ZnO) thin films were deposited by pulsed laser deposition technique for making ZnO/Al/SiO2/Si Bulk and Surface Acoustic Wave (BAW and SAW) transducers. The aim is to improve the piezoelectric properties of the ZnO films, which are strongly linked to their texture and microstructure. ZnO films with a wurtzite structure were deposited on […]
