Abstract
A fluidic chip device configured for processing a fluid, wherein the fluidic chip device comprises a plurality of layers laminated to one another, wherein at least a part of the layers comprises a patterned section of an alternating sequence of bars and fluidic channels for conducting the fluid under pressure, the patterned section being configured for being displaceable in response to the pressure, and a pressure detector responding to the displacement of the patterned section by generating a detector signal being indicative of a value of the pressure.
Claims21
A fluidic chip device configured for processing a fluid, the fluidic chip device comprising:
- a plurality of layers laminated to one another;
- wherein at least a part of the layers comprises a patterned section of an alternating sequence of bars and fluidic channels for conducting the fluid under pressure along a resultant flow direction, the patterned section having a length along the resultant flow direction and being configured for being displaceable in response to the pressure such that the length of the patterned section changes in response to the pressure;
- and
- a pressure detector configured for responding to the displacement of the patterned section by generating a detector signal being indicative of a value of the pressure.
A method of detecting information indicative of a pressure value of a fluid flowing in a fluidic chip device configured for processing the fluid, the fluidic chip device comprising a plurality of layers laminated to one another and a pressure detector being at least partially integrated within the plurality of layers, wherein at least a part of the layers comprises a patterned section of an alternating sequence of bars and fluidic channels for conducting the fluid under pressure along a resultant flow direction, the patterned section having a length along the resultant flow direction, the method comprising:
- displacing the patterned section in response to a pressure applied by conducting the fluid under the pressure through the fluidic channels, wherein the length of the patterned section changes in response to the pressure;
- and
- detecting the displacement of the patterned section by generating, by the pressure detector, a detector signal being indicative of a value of the pressure.
