摘要： This invention relates to a systems and methods of controlling the flow of a fluid in a capillary or microfluidic channel. A first pair of electrodes can influence the wetting of a fluid front at a relatively hydrophobic surface in the channel. A second pair of electrodes can electrolytically generate a bubble that can stop fluid flow when it contacts the hydrophobic surface. Flow of a fluid in a channel can be stopped on contact with the hydrophobic surface and restarted when an electrostatic field reduces the contact angle of the fluid at the hydrophobic surface. The electrostatic field can be removed and the fluid stopped again when an electrolytically generated bubble contacts the hydrophobic surface to reestablish the blocking contact angle of the fluid, gas and surface.

摘要： This invention relates to micromachined fluid ejector arrays having a fluid reservoir bounded at one side by an elastic membrane having scalable arrays of orifices arranged between concentric piezoelectric transducers, and bounded at another side by a top cover supported by surrounding walls. By actuating neighboring concentric piezoelectric transducers, the scalable array of orifices arranged between the actuated neighboring concentric piezoelectric transducers deflect to eject fluid droplets. Also disclosed is a micromachined fluid ejector array having a fluid reservoir bounded at one side by an elastic membrane having scalable arrays of orifices arranged between concentric piezoelectric transducers, and at another side by a top cover supported by surrounding walls with a piezoelectric layer bonded on top of the top cover. By actuating the piezoelectric layer, the scalable arrays of orifices arranged between the neighboring concentric piezoelectric transducers deflect in phase to eject fluid droplets.
