Design optimization of an electromagnetic actuation based valveless micropump for drug delivery application

摘要

A valveless micropump based on an electromagnetic actuation for drug delivery application has been designed. The parametric studies are performed to examine the effects of the divergence angle, neck width, diffuser length, height and diameter of the pump chamber and diaphragm thickness on the flow rate. Furthermore, an optimal design of the micropump is identified, and the proposed micropump has been fabricated. Experiments are performed to validate simulation results in terms of flow rate versus frequency and flow rate versus back pressure. The proposed micropump is polymer based and thus suitable for low-cost and disposable applications.
