Numerical analysis of thermal and electrohydrodynamic effects in travelling-wave dielectrophoretic devices

Travelling-wave dielectrophoretic phenomena involving cell detection and manipulation are very interesting for biomedical and biotechnological applications. However, electrohydrodynamic phenomena may interfere with the action of dielectrophoresis. The main goal of our study is to calculate the interplay of these effects. In so doing, we have been able to go beyond the order-of-magnitude estimations, which were available in the literature. In this framework we have taken into account the effects of using square signals, which calls for a calculation of the combined polarisability effects due to...
