Abstract
The present invention relates to a device for controlling fluid movements. The device includes a fluid guiding device, and a fluid moving device which includes polymers whose hydrophilic and hydrophobic properties can be selected under the action of an external force. The fluid moving device comprises a plurality of polymer elements whose hydrophilic and hydrophobic properties can be selected. The elements are arranged along the guiding device and at least one actuating unit is used to generate the external force.
