A tool for monitoring piezoelectric micro-pumps
Résumé
Piezoelectric micro-pumps are largely used in drop on demand applications for medical purpose and in the printing industry. In order to diagnose and control such a system, a non-linear model has been developed to predict the velocity of the ejected drop. We show here that data from experiments are in good agreement with our model predictions, showing that the ejection velocity is strong a function of the applied voltage.
