| description | •We develop a wirelessly powered micropump that is operated using frequency-controlled resonant heater.•Wireless micropump based on thermo-pneumatic principle is reported for the first time.•The developed micropump has minimal/no moving part that increases the functional reliability of the device.•The liquid is pushed from a pre-filled reservoir to the outlet port based on the volume expansion of a trapped air upon heating operation.•The developed device has volume control feature based on single stroke or multiple strokes pumping with volume variation of ∼2.8% between each stroke.•Numerical simulation and experimental verification performed to verify the heat distribution to the reservoir where the liquid/drug stored is minimal.
This paper reports a novel, wirelessly powered micropump based on thermo-pneumatic actuation using a frequency-controlled heater. The micropump operates wirelessly through the energy transfer to a frequency-dependent heater, which was placed underneath the heating chamber of the pump. Heat is generated at the wireless heater when the external magnetic field is tuned to the resonant frequency of the heater. The enclosed air in the chamber expands and forces the liquid to flow out from the reservoir. The developed device is able to pump a total volume of 4ml in a single stroke when the external field frequency is tuned to the resonant frequency of the heater at the output power of 0.22W. Multiple strokes pumping are feasible to be performed with the volume variation of ∼2.8% between each stroke. Flow rate performance of the micropump ranges from 1.01μL/min to 5.24μL/min by manipulating the heating power from 0.07W to 0.89W. In addition, numerical simulation was performed to study the influence of the heat transfer to the sample liquid. The presented micropump exclusively offers a promising solution in biomedical implantation devices due to its remotely powered functionality, free from bubble trapping and biocompatible feature. |
