A Novel Reconfigurable Multi-Input Multi-Output (MIMO) Micropump for Micro Drug Delivery System

Micropumps are important bio-MEMS (bio-Microelectromechanical Systems) devices used to drive microfluid to flow along microchannels. They are widely used for Micro Total Analysis System (μTAS), Lab-on-a-chip, micro drug delivery systems and many other applications. A typical micropump has only one inlet and one outlet. In this poster, a reconfigurable multi-input multi-output (MIMO) micropump for micro drug delivery application is reported. The proposed micropump has six inlets and six outlets. The micro-valve in each inlet and outlet can be controlled individually. As a result, microfluid can be pumped in from any (or multiple) inlets(s), and pumped out to any (or multiple) outlet(s). Piozoelectric actuation is used in the micropump design. The proposed MIMO micropump can be used for multi-drug delivery system and other applications
