In this study, the droplets in inkjet printing have been simulated based on mechanical parameters including temperature and pressure changing and also the chemical condition contain dielectric of various solvent materials has been investigated. Basically in viewpoint of electromechanical parameters we simulated and divided the inkjet printing into the piezoelectric type and thermal type, and as our results shows, each type has advantages and disadvantages. In this paper the piezoelectric types which has features such as; ink delivery quantity, driving control, controlling of droplet size based on color representation, generating heat and superb reliability have been introduced. By this work, we exhibit the deformation of piezoelectric elements is applied in two ways, consist of thickness deformation and sliding deformation. This chamber is included in a small slot that is created through two piezoelectric crystal plates .In addition the voltages inserted to the piezoelectric walls on both sides cause deformation mode. Due to this operation shear mode deformation occurs to both walls and via the ink pressure chamber, ink drops are delivered. Several inks applied as a dielectric material layers for conductive track in electrochemical sensors. Thus, passivation of printed sensors and deposition of adhesives can be achieved simultaneously. In this work, the presented method for the printing of UV-curable adhesive and dielectric inks demonstrates a rapid facile prototyping process.
