Problems solved by technology

[0009] However, the disadvantage of using the micropump assembly 11 of US 2003 / 0231967 and of using a micropump in general is that it has to be integrated in a microfluidic system in some way
This means increasing the size of the microfluidic system

Embodiment Construction

[0057] The present invention will now be described with reference to particular embodiments and certain drawings but the invention is not limited thereto but only by the claims. Any reference signs in the claims should not be construed as limiting the scope. The shown figures are only schematic and not restrictive. In the drawings, the size of some of the elements is exaggerated and not drawn on scale for illustrative purposes. When the term "comprising" is used in the present description and claims, it does not exclude the possibility of the presence of other elements or steps. When an indefinite or definite article is used to introduce a singular noun such as "a" or "an", "the", it may include a plural of that noun unless specifically stated otherwise.

[0058] Furthermore, where the terms first, second, third etc. are used in this description and claims to distinguish similar elements, they do not necessarily imply a sequential or chronological order. It is to be underst...

Abstract

The present invention provides micro-fluidic systems, a method for the manufacturing of such a micro-fluidic system and a method for controlling or manipulating a fluid flow through micro-channels of a such a micro-fluidic system. Herefore, an inner side of a wall of a microchannel is provided with actuator elements which can change shape and orientation as a response to an external stimulus. Through this change of shape and orientation the flow of a fluid through a microchannel may be controlled and manipulated.

Description

technical field [0001] The present invention relates to microfluidic systems, methods for fabricating such microfluidic systems and methods for controlling or manipulating fluid flow through microchannels of such microfluidic systems. Such microfluidic systems can be applied in microchannel cooling systems in biotechnological and medical applications as well as in microelectronics applications. The microfluidic system according to the invention is compact, inexpensive and easy to process. Background technique [0002] Microfluidics involves a multidisciplinary field including physics, chemistry, engineering and bioengineering, which studies the behavior of fluids with volumes thousands of times smaller than usual liquid droplets. Microfluidic components form the basis of so-called "lab-on-a-chip" devices, or networks of biochips, capable of handling microliter or nanoliter volumes of fluids and performing highly sensitive analytical measurements. The fabrication techniques...
