20.500.12556/RUL-129499 A strip-type microthrottle pump modeling, design and fabrication A novel design for a strip-type microthrottle pump with a rectangular actuator geometry is proposed, with more efficient chip surface consumption compared to existing micropumps with circular actuators. Due to the complex structure and operation of the proposed device, determination of detailed structural parameters is essential. Therefore, we developed an advanced, fully coupled 3D electro-fluid-solid mechanics simulation model in COMSOL that includes fluid inertial effects and a hyperelastic model for PDMS and no-slip boundary condition in fluid-wall interface. Numerical simulation resulted in accurate virtual prototyping of the proposed device only after inclusion of all mentioned effects. Here, we provide analysis of device operation at various frequencies which describes the basic pumping effects, role of excitation amplitude and backpressure and provides optimization of critical design parameters such as optimal position and height of the microthrottles. Micropump prototypes were then fabricated and characterized. Measured characteristics proved expected micropump operation, achieving maximal flow-rate 0.43 mL min$^{−1}$ and maximal backpressure 12.4 kPa at 300 V excitation. Good agreement between simulation and measurements on fabricated devices confirmed the correctness of the developed simulation model. microthrottle pump micropump numerical simulation 3D fully coupled model hyperelastic model PDMS lab on chip COMSOL fluidics optimization mikročrpalke numerična simulacija 3D popolno sklopljen model PDMS laboratorij na čipu COMSOL mikrofluidika optimizacija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-09-02 09:55:57 2021-09-02 09:55:58 2022-09-08 04:08:53 0000-00-00 00:00:00 2013 0 0 Str. 3092-3108 iss. 3 Vol. 13 2013 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 681.5:621.38 1424-8220 10.3390/s130303092 9729620 RAZ_Pecar_Borut_2013.pdf RAZ_Pecar_Borut_2013.pdf 1 555D7F14A44DEA8BD90F4AD24640AE80 fbe1134e330213807b1daf52482e36f172762796b813d42e895eaf0130343494 3bd41d11-0bc3-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=146480 https://www.mdpi.com/1424-8220/13/3/3092 0 328cf9ae-0bc3-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=146479 Fakulteta za elektrotehniko 0 0 0
