digital micropump by using electrowetting on dielectric

摘要

The present invention 'of the dielectric above electrowetting phenomenon in the application, which imposes a direct target fluid momentum dynamic pump (dynamic pump) system as a digital micro-pump, the cross-sectional area of the flow channel, the main channel of the transport fluid and the target, and the mobile number of the droplets through the inside the main channel, substantially corresponding to the first moving distance of the drop It relates to digital micro-pump using electrowetting to precisely control the volume of the dielectric above the transfer target fluid in proportion to the area between the electrodes. More specifically, the present invention is the main channel to the first fluid inlet hole and the first fluid entering the transfer target is connected to the outlet hole from flowing out; The inlet hole and connected to the sub-inlet hole and the sub-outlet hole each connected to the main channel between the outlet hole, the first fluid and the second fluid is filled the sub-channel that is immiscible; Drop of the second fluid is inserted in the main channel between the sub-inlet hole and the sub-outlet hole; And are arranged along one side of the main channel provides a digital micro-pump using the electro-wetting phenomenon of the dielectric above including a first electrode applied to the driving voltage.
