AC electroosmosis is a convenient valveless method to pump liquids, whilst avoiding electrolysis and gas generation. Basic designs presented in the literature often have limited velocity or pressure capabilities. This paper reports a simple approach to the ...
This paper reports on the fabrication and experimental characterisation of improved design AC eletroosmotic micropumps. Since the first study and analysis of AC electroosmosis by Ramos et al. [1], many devices have been fabricated and tested [2]. The basic ...
Standalone integrated microfuidic systems require pumping elements. Electro-osmosis (EO) is an e"ective method of actuating liquids [1,2]. ACEO exploits much lower potentials and, by using alternating fields, overcomes the issues of electrolysis and gas ge ...
Many popular micropumps implement moving parts that presents serious drawbacks. This is one of the reasons for the growing interest in valveless micropumps. Pumps exploiting AC electric fields are investigated here. Theoretical results are recalled and the ...
This thesis presents the fabrication and characterisation of AC electro-osmotic micropumps with a simple design and velocity generation enhanced by about four times with respect to devices with simpler designs. Electro-osmosis is a convenient and effective ...
