| 摘要 |
The present invention relates to a device for controlling fluid movement. The device comprises: a) fluid guiding means (100, 200, 300); b) fluid moving means (120, 220, 320) comprising polymers having hydrophilic and hydrophobic properties that can be selected under the action of an external force, said fluid moving means comprising a plurality of polymer elements (130, 230, 330) whose hydrophilic and hydrophobic properties can be selected, said polymer elements being arranged along the fluid guiding means; c) at least one actuating unit (140, 240, 340) which generates said external force. Application: ink jet printing. <IMAGE> |
