Abstract
A micro fluidic device comprises a laminate structure, comprising a plurality of individual layers. At least one layer comprises a micro fluidic channel structure and at least on one side of said layer a further layer is arranged comprising a three-dimensional (3D) micro structure such that the 3D micro structure is influencing a flow characteristic of a fluid within the micro fluidic channel structure.
Claims15
A method for producing a micro fluidic device comprising:
- forming a structured pattern in a first substrate layer comprising an anisotropic material, said structured pattern being in a plane with a surface of said first substrate layer;
- and
- forcing said structured pattern out of said plane with said surface to form a 3-dimensional (3D) micro structure with said first substrate layer, said 3D micro structure being configured to influence flow of a fluid flowing through said micro fluidic device.
A micro fluidic device comprising a laminate structure comprising a plurality of individual layers of which:
- a first layer comprises a micro fluidic channel structure, and
- a second layer comprising a 3D micro structure configured to influence a flow characteristic of a fluid within the micro fluidic channel structure is provided adjacent said first layer, said 3D structure being formed from a structured pattern of an anisotropic material.
