Electrochemical Pump for Handling Small Quantities of Liquid based on the Water Electrolysis Process
AbstractThe field of electrochemical pumps is old, and during the history there are many interests concerning the electrochemical pumps. The electrochemical pumps with liquid can find their application in various areas, especially in the biomedical engineering. In order to use small amounts of liquids, in technique there are met certain solutions known as electrochemical micropumps, which have different disadvantages. The present paper propose a way to achieve an electrochemical pump for handling small quantities of liquid, pump based on the electrolysis process and also a modeling of its operating. The experimental data demonstrate that the pump flow rate is linear in relation to current intensity, which means that for a certain type of construction of pump, knowing the flow-current characteristic it may be prescribed a certain flow rate by current adjustment. A fine adjustment of current determines a fine adjustment of flow rate (number of liquid drops released by the pump during a given time interval). Such a pump could be used in biomedicine, for example. Ill. 6, bibl. 3, tabl. 1 (in English; abstracts in English and Lithuanian).
