Micropump for fluidic applications

Non-Confidential description of the invention

The present invention relates to the field of drug delivery system using micro-pump, and more particularly to a system and process for manipulation of fluids in a micro-pump chamber for controlled fluid discharge with low retainablity and reduced reverse flow. It is a peristaltic micro-pumping system comprising a micropump with at least one fluid chamber or channel of optimized geometry consisting of one fluidic layer and other control layer containing blister pockets in direct connection with inlet and outlet means, an actuation means, a means for power input, a means for wave form generation coupled to the amplifier operating at a lower output voltage, wherein the geometry of the fluid chamber is optimized using numerical simulations and then fabricated to a fluid chamber of surface roughness of about 460nm on PMMA substrate by laser micromachining and wet chemical etching.
