ELECTROCHEMICAL MICROPUMP WITH PELTIER ELEMENT

摘要

The invention relates to an electrochemical micropump with Peltier element meant to circulate low quantities of fluid. According to the invention, the micropump comprises a cylindrical housing (1) wherein there are placed two sylphons (2 ans 2') filled with liquid (3 and 3') separated by a Peltier element (4) such that when the upper surface thereof is heated, the sylphon (3) expands and determines the discharge of the agent to be circulated from the upper cavity through a microchannel (6), this time the lower surface of the Peltier element (4) is cooled, determining the compression of the active liquid (3') and the sylphon (2') which leads to the filling of the lower cavity with an agent to be circulated through a microchannel (6') which is in contact with an outer container (7), and to the reversal of the polarity of the voltage supplying the Peltier element (4), to obtain the reversal of the driving direction of the micropump.
