Abstract :
In this paper we have addressed the various aspects of design and simulation of MEMS based micro-pump, microvalve and micro-needles. Operating frequency and flow rate of the piezoelectrically actuated micro-pump was calculated using data from simulations. The PDMS flap based micro-valve operates like a microfluidic diode and prevents back flow of fluid. The silicon micro-needles can be used to deliver drugs into the patient´s body and sample body fluids. These devices can be utilized to develop an automatic drug delivery system that has potential use in the healthcare sector.
