Abstract
In this work, a passive ortho-planar microvalve design is investigated. The component is conceived to be integrated in micropumps and microfluidic systems. It is
very compact and it can be realized through standard planar machining techniques, such as laser
rapid prototyping or MEMS surface micromachining.
Analytical and Finite Element coupled approaches are used to describe the microvalve
response to the fluid flow. A validation of the models is successfully carried out
with respect to literature data for silicon microvalves. The proposed analytical model
well describes the hydraulic resistance. Eventually, a calibration through a limited
number of numerical simulations can be done. Subsequently, polymeric prototypes are
realized and tested. The manufactured microvalves are effective in flow rectification and a power
law Q − ∆pV trend is evidenced. As expected, deviations are found with respect to the modeled
ideal response. This seems to be due to tolerances in assembly and high structure
compliance.
