Joule Heating Effects on Insulator-based Dielectrophoresis

چکیده
ABSTRACT We present an experimental and numerical study of Joule heating in a polymeric insulator-based dielectrophoresis (iDEP) device. In this study, we used a microscale thermometry technique based upon the temperature-sensitive fluorescence of Rhodamine B dye to monitor the fluid temperature within our iDEP microfluidic devices. We then complemented our experiments with 3D finite element simulations of the fluid flow, electric field and heat transport to analyze the temperature distributions in the fluid and polymer regions. Our investigation reveals that Joule heating has a significant impact on the fluid and particle behavior within iDEP devices.
