Design of efficient MEMS based actuator for drug delivery applications

Abstract

The advancements in drug delivery system are of great value when the betterment of human life comes into one's mind. Although so many improvisations have already been done over the years, but many challenges remain in this area. Typically, a drug delivery system consists of drug reservoir and a micropump and micropump requires an actuator for the purpose of pumping the fluid. In the present work, piezoelectric actuator is used because of its faster response time in generating large amount of force. The aim of the project is to design such an efficient piezoelectric actuator based on MEMS technology for delivering required amount of the fluid to the target site. For this, here, the software that is being used is COMSOL 4.3 Multiphysics.
