Wireless powered thermo-pneumatic micropump using frequency-controlled heater

摘要: Abstract This paper reports a novel, wirelessly powered micropump based on thermo-pneumatic actuation using frequency-controlled heater. The operates through the energy transfer to frequency-dependent heater, which was placed underneath heating chamber of pump. Heat is generated at wireless heater when external magnetic field tuned resonant frequency enclosed air in expands and forces liquid flow out from reservoir. developed device able pump total volume 4 ml single stroke output power 0.22 W. Multiple strokes pumping are feasible be performed with variation ∼2.8% between each stroke. Flow rate performance ranges 1.01 μL/min 5.24 μL/min by manipulating 0.07 W 0.89 W. In addition, numerical simulation study influence heat sample liquid. presented exclusively offers promising solution biomedical implantation devices due its remotely functionality, free bubble trapping biocompatible feature.
