Title:
ELECTROOSMOTIC MICROPUMP APPARATUS AND ELECTROOSMOTIC MICROPUMP APPARATUS GROUP
Document Type and Number:
WIPO Patent Application WO/2021/047529
Kind Code:
A1
Abstract:
The present invention relates to the technical field of microfluidics, and specifically relates to an electroosmotic micropump apparatus and an electroosmotic micropump apparatus group. The electroosmotic micropump apparatus in the present invention comprises fluid micro channels and a microneedle electrode; each fluid micro channel is used for communicating a micro flow channel inlet with a micro flow channel outlet for pumping a fluid; the microneedle electrode comprises a first microneedle type electrode and a second microneedle type electrode that are respectively provided at the micro flow channel inlet and the micro flow channel outlet; the first microneedle type electrode and the second microneedle type electrode are oppositely arranged; moreover, neither of the first microneedle type electrode and the second microneedle type electrode is in conduction with the fluid micro channel. The electroosmotic micropump apparatus of the present invention can provide a parallel and uniform electric field for the interior of the fluid micro channel and generate a stable electroosmotic driving force, and can solve the hydrolysis problem of the surface of an electrode, thereby greatly improving the stability of the running of a micropump and prolonging the service life of the micropump.
