Abstract
The aim of the invention is to convectively move at least one liquid in a channel of a microsystem which comprises a predetermined channel direction. To this end, the liquid is, in a partial section of the channel, subjected to an electric field gradient and optionally to a thermal gradient. The gradients are generated in the partial section corresponding to a predetermined field direction, whereby the field direction differs from the channel direction.
Claims20
A process for the convective movement of at least one fluid in the channel of a microsystem having a predetermined channel direction, wherein the fluid is subjected in at least one section of the channel to an electrical field gradient which is generated with electrical fields in the section according to a predetermined field direction, with the field direction deviating from the channel direction, and the fluid being moved under the effect of the field gradient in a direction deviating from the channel direction.
A device for convective movement of a fluid in a fluidic microsystem, comprising a channel with a predetermined channel direction in the microsystem, with an electrode arrangement being provided in at least one predetermined section in the channel and the electrode arrangement being set up to form an electrical field gradient along a predetermined field direction, wherein the electrode arrangement is formed in such a way that the field direction deviates from the channel direction.
