Abstract

The invention discloses a micropump structure based on PVC-gel flexible driving. The micropump structure comprises a pump body and a PVC-gel flexible driving unit; a groove, a water inlet and a wateroutlet are formed on the pump body; the PVC-gel flexible driving unit is arranged in a cavity body to form the micropump structure; and the PVC-gel flexible driving unit is used for generating creep deformation toward an anode under the action of an electric field so as to cause changes in the internal capacity and pressure of the cavity body to realize fluid pumping. By utilizing a resin materialas the pump body of a micropump, liquid in various properties can be pumped, and by adopting a PVC-gel film as a flexible driving vibrator, pumping of the micropump can be realized simply by applyingalternating voltage without complicated additional equipment, so that the field application of the micropump is extended.

Description

technical field [0001] The invention belongs to the technical field of intelligent materials and intelligent structures, and in particular relates to a micropump structure based on PVC-gel flexible drive. Background technique [0002] In recent years, research work on micropumps can be described as diverse. A lot of research work has been done on the structure, process materials and drive of the micropump. The micropump is mainly composed of pump body, inlet and outlet (including valve type and valveless type) and driver. The driving method has become the key technology for the practical application of micropumps. [0003] Piezoelectric-driven micropumps are based on the piezoelectric properties of piezoelectric crystals to drive membrane vibrations to pump fluid. Common piezoelectric materials include piezoelectric sheets, PZT piezoelectric stacks, and piezoelectric films. Its disadvantages are high driving voltage, small amplitude, and difficulty in self-priming, which ...
