A Design Analysis of High Flow Rate Serial Connection Multi-Chamber Piezoelectric Micropump for Drug Delivery System

High flow rate of Lead Zirconate Titanate (PZT) actuated serial-connection multi-chamber piezoelectric micropumps (SCMCP micropumps) design for insulin therapy system was proposed. Four chambers in serial-connection micropumps with cantilever valves were introduced. The proposed design of micropumps will be made of biocompatible and non-toxic materials to ensure its safety. The specification of the proposed design of micropumps have a high flow rate of 10.7 mL/min and a backpressure of 34.3 kPa at driving voltage V

36 V and 200 Hz operating frequency, respectively. Furthermore, the micropumps design was simulated by a simulations software tool to further study the pump model. The flow rate and static stress were investigated by software simulation.
