Electro-thermal micro-pumps: exploiting structural polarizations at smeared interfaces

Stubbe M., Gimsa J., University of Rostock, DE

Various designs for new AC electro-thermal micro-pumps (ETµPs) are present which exploit AC electro-kinetic forces acting on smeared charges in the bulk of fluids in the presence of a temperature gradient. Measurements of the pump [...]

Exploiting structural polarization effects for the AC-electrokinetic manipulation of objects and media in cell chips

Gimsa J., Stubbe M., University of Rostock, DE

AC fields induce polarization charges at the structural interfaces inside inhomogeneous media (Maxwell-Wagner polarization). In suspensions or emulsions of micro and nano objects such as particles, oil droplets, air bubbles and biological cells, these structures [...]
