Drop stirring flow under EWOD and EHD actuation: a new step towards biological sample preparation

Résumé

This paper addresses electrically-induced drop mixing. The configuration studied here is typical of electrowetting on dielectrics (EWOD) – based actuation with a drop staying on a hydrophobic dielectric substrate. Application of normal and tangential components of an electric field at and along the interface is found to give rise to an electric surface stress able to pump drop vortices (electrohydrodynamics of Taylor-Melcher type) with a remarkable efficiency.
