A Highly Programmable Magnetic Micropump

A cheap, small, convenient, reliable, and durable lab-on-a-chip is needed for various scenarios in practical applications. The authors hope to use the chip only after plugging a mobile phone. An ideal micropump design obtained by simplifying theory, reducing 1 mm (oscillator pump, O-pump), external device (actuator) 5 mm, power 10 mW. This system costs ?$10 can work harsh fluid environments (such as animal cell culture) an extended period (a few months of testing). MP3 player drives two O-pumps programmable playlist. O-pump permanent magnet positive sphere open space, which not easy block rolls freely without wear. Only controlled magnetic field, avoids interference from current, electric chemical activity. driven vibrating motion, or sealed channels, with no unique materials other equipment. debris, bubbles, fibers blood viscosity do affect pump's function. be applied different scenarios, such automatic cultivation stem cells point-of-care devices.
