Abstract
A microfluidic structure with an electrically controlled pressure source is shown. The pressure source is an electrolyte connected with electrodes. Dissociation of the electrolyte generates the pressure, which is used to obtain a valve-like or pump-like behavior inside the microfluidic structure. A process for manufacturing the microfluidic structure and a method to circulate fluids in a microfluidic channel are also described.
