Abstract
A novel pump design relying on two-liquid viscous drag to pump nonconducting liquids is presented. A conducting pumping liquid driven by electroosmosis (EOF) drags a nonconducting working liquid by viscous forces. In particular liquids such as oil or ethanol, which normally cannot be moved by an EOF, can be pumped through the system. The pump is operated in the low-voltage regime. The flow-rate/pressure (Q-p) characteristic of the pump depends largely on achievable geometrical dimensions. This paper presents a complete theoretical and modeling study of the novel design.
