This paper presents a resonantly-driven and high-performing piezoelectric micropump, which is favorable for the fuel delivery system. The micropump consists of a resonance-driven vibrator, two simple polydimethylsioxane (PDMS) check valves and compressible spaces. The PDMS check valve increases the working stability and reduces the leakage rate. The performance of the micropump is significantly improved...
An efficient fuel delivery system with low power consumption is necessary to provide an adequate amount of fuel for fuel cells. This study presents the design concept, fabrication process, dynamic analysis, and experimental results of a piezoelectric micropump with high flow rate, high pumping pressure, and lower power consumption, which is favorable for the fuel delivery system. The micropump consists...
