This paper analyses two optimzization procedures: onze based on genzetic algorithms and thze other oni differential evolution. We apply thtese algorithms on a particular problemn from the field of microfluidics in order to demozonstrate how thley cani be used in design optimnization. The improvement of tlhe resuilts, and also the simplicity and flexibility of the algorithms encoutrages us to suggest the use of these techniques in other problems from other areas in MEMS design.
Performances of a pneumatically actuated micropump are described. Simulation results combined to an analytical model are used to optimize the micropump design in order to obtain a working frequency of 10 Hz for pneumatic pressure varying between 0.1 -6 Bar. A pneumatic chamber is placed between a polymer membrane to be actuated, and microchannels connected to a vacuum system. Time for pressurizing cycle and vacuum cycle asfunction of design parameters and relative pressure are calculated.
This paper presents a modeling technique based on the integration in the classic deterministic simulation methods of probabilistic computational techniques such as uncertainty analysis and sensitivity analysis. As study case, it is presented a micro-comb resonator that is actuated electrostatically to vibrate in the plane parallel to the substrate. A deterministic Finite Element coupled electromechanical analysis is performed to evaluate the mode shapes and the corresponding eigenfrequencies of the mobile mass and afterwards a Monte Carlo simulation is used to determine the dispersion of the eigenfrequency of the mode shape of interest in function of the variations of the input parameters. The scatter of the results is analyzed and then it is presented a sensitivity analysis for establishing which of the input parameters have more influence on the variability of the microresonators performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
