Abstract
A microfluidic device includes at least two layers arranged one above the other, a membrane which is arranged between the at least two layers, a cavity in one of the at least two layers, and a channel in the other of the at least two layers. The membrane is arranged so as to be expandable between the cavity and the channel. The membrane is expandable into at least one specified displacement volume.
Claims17
A microfluidic device, comprising:
- at least two layers arranged above one another;
- an elastic diaphragm arranged between the at least two layers;
- a cavity arranged in a first layer of the at least two layers;
- and
- at least one duct arranged in a second layer of the at least two layers, the at least one duct configured to act upon the diaphragm with pressure,
- wherein the diaphragm is arranged so as to be expandable into at least one stipulated displacement volume.

A method for producing a microfluidic device, comprising:
- arranging a cavity in a first layer of the microfluidic device;
- and
- arranging at least one duct in a second layer of the microfluidic device,
- wherein at least two layers, including the first layer and the second layer, are arranged above one another and an elastic diaphragm, arranged between the at least two layers, is arranged so as to be expandable into at least one stipulated displacement volume,
- wherein the at least one duct is configured to act upon the diaphragm with pressure, and
- wherein at least one of the cavity and the at least one duct is formed by at least one of milling, injection molding, and hot pressing.
3 more elements
