A Study on the Materials Properties of Piezoelectric Ceramics Used in Jetting Apparatus
In this study, specially used in fluidic jetting apparatus, the electrical properties of piezoelectric ceramics were investigated by the resonance method and from its vibratory motion point of view. The piezoelectric ceramics were a rectangular bar type bulk and estimated by their piezoelectric constants, for example, electromechanical coupling factor, piezoelectric strain constant and so on. The measured values were compared with the displacement by the Laser Doppler Vibrometer analysis and with the droplet properties.
