Abstract. A model of a microfluidic biomedical device has been proposed, using the magnetocaloric effect of the FeRh alloy to control the wetting of modified channels using a thermosensitive polymer, PNIPAM. This approach to local cooling offers significant advantages over traditional resistance heating methods, as it allows both cooling and heating of microchannels at high speed and with low inertia, which is especially important for temperature control in microfluids. Through computer simulation, it has been shown that when a magnetic field of 1.8 T is applied to the microchannel coated with thermoresponsive PNIPAM, the temperature can be cooled to a critical solubility temperature (> 32°C) within 0.04 seconds, much faster than resistive or thermoelectric cooling. The proposed method has the potential to generate microdroplets for a variety of applications in biomedicine and pharmacology.
Key words: point cooling, magnetocaloric effect, FeRh, microfluidics, thermosensitive polymers, PNIPAM.
