The pump is designed to have three major components, namely a lower glass substrate patterned with a copper micro-coil, a microchannel, and an upper glass cover plate attached a magnetic PDMS diaphragm. When a current is passed through the micro-coil, an electromagnetic force is established between the coil and the magnetic diaphragm. The resulting deflection of the PDMS diaphragm creates an acoustic impedance mismatch within the microchannel, which results in a net flow. In performing the analysis, simulated models of the magnetic field, the diaphragm displacement and the flow rate are developed using Ansoft\/Maxwell3D, ANSYS FEA and FLUENT 6.3 CFD software, respectively. Overall, the simulated results reveal that a net flow rate of 52.8 \u03bcL\/min can be obtained using a diaphragm displacement of 31.5 \u03bcm induced by a micro-coil input current of 0.5 A. The impedance pump proposed in this study provides a valuable contribution to the ongoing development of Lab-on-Chips (LoCs) systems.<\/jats:p>","DOI":"10.3390\/s100404040","type":"journal-article","created":{"date-parts":[[2010,4,21]],"date-time":"2010-04-21T11:20:48Z","timestamp":1271848848000},"page":"4040-4052","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Design and Analysis of Impedance Pumps Utilizing Electromagnetic Actuation"],"prefix":"10.3390","volume":"10","author":[{"given":"Yu-Hisang","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Mechanical and Automation Engineering, Da-Yeh University, 515 Changhua, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yao-Wen","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Automation Engineering, Da-Yeh University, 515 Changhua, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chien-Hsiung","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Vehicle Engineering, National Pingtung University of Science and Technology, 912 Pingtung, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chia-Yen","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Engineering, National Pingtung University of Science and Technology, 912 Pingtung, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lung-Ming","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Materials Engineering, National Pingtung University of Science and Technology, 912 Pingtung, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2010,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1121","DOI":"10.1007\/s00542-005-0512-x","article-title":"Membrane microcantilever arrays fabrication with PZT thin films for nanorange movement","volume":"11","author":"Zhu","year":"2005","journal-title":"Microsyst.
