Abstract

A low cost piezoelectric micropump was designed and
fabricated to supply fluid flow rate in micro-sizes and for use in medical
purposes. It was designed as disposable in order to prevent contamination and
infection. The micropump was fabricated with the Objet260 Connex3
multi-material 3D printer, which was very precise and sensitive. The
piezoelectric was selected as an actuator to drive the diaphragm of this
micropump. The piezoelectric diameter was 14mm, the thickness was 200 µm and
the operating voltages were between 5V-55V. According to the experiments
results, the air in the chamber caused reduction of the net flow rate of the
micropump. Therefore, we eliminated the air inside the chamber with ethanol
before the experiments. In the proposed micropump, we obtained the highest net
flow rate and the maximum displacement of diaphragm at 55V that were 40.3ml/min
and 2.64µm respectively.
