| Abstract | This paper describes the design of a normally closed, electrodynamic microvalve. Magnetic forces between a permanent magnet in the valve cover and a soft magnet in the valve seat hold the valve closed. The combination of electrodynamic actuation and a mechanical restoring spring are used to open the valve. A device model and a design optimization strategy using COMSOL Multiphysics and the MATLAB Optimization Toolbox are presented. The theoretical performance of the optimized valve is calculated and shows that a maximum static pressure approaching 1 MPa is achievable. |
