  • Novel architecture for entrapment of elastomeric membranes in microfluidic systems

    Creator:
    Blackwell, Edward P.
    Abstract:
    This thesis presents a novel microlamination architecture that enables the large scale integration of valves into low cost micro energy and chemical systems via membrane entrapment. Polycarbonate layers embossed with microfluidic channels were bonded by ultrasonic welding of raised embossed protrusions that penetrate though the PDMS membranes. The bonding pressure...

    Abhinkar, Bindiya S.
    Abstract:
    PDMS membrane-based microvalves are becoming increasingly more important for the control of fluid flow within MECS applications such as microreactors used to synthesize nanoparticles and biological macromolecules. The motivation for pursuing PDMS membrane-based microvalves is for implementing a plug flow microreactor to simulate slug flow yielding a narrower residence time...

  • Force Prediction in the Compression Sealing of an Ultra-thin Elastoviscoplastic Membrane

    Creator:
    McNeff, Patrick Scot
    Abstract:
    The objective of this paper is to demonstrate a method for mechanically characterizing a 25 μm thick elastoviscoplastic hemodialysis membrane and for quantifying the force required to use that membrane in compression sealing. First, methods are developed for mechanically characterizing the thin elastoviscoplastic membrane. Then, a finite element model is...
