Abstract

Disclosed is a fluidic device including at least: a) a solid matrix; b) a textile component, embedded in the matrix and mechanically cohesive with the matrix; c) at least one channel embedded in the matrix and entangled with the textile component, the channel being at least partly open. A method for making a fluidic device includes providing a textile component including support fibers and at least a movable fiber entangled with the textile, embedding at least part of the textile and part of the movable fiber, in a matrix precursor material, applying a treatment in order to obtain a solid matrix.

First claim

1 . A fluidic device comprising at least:
a/ a solid matrix ( 5 , 36 ), b/ a textile component ( 4 , 41 ), embedded in said matrix, c/ at least one channel ( 6 , 10 , 37 , 38 , 43 , 45 ) embedded in said matrix, said channel having a multiplicity of underpasses and overpasses with at least some fibers of said textile component ( 4 , 41 ), and said channel ( 6 , 10 , 37 , 38 , 43 , 45 ) being a tube or a pipe along at least part of its length.

2 . A device according to claim 1 , wherein said channel ( 6 , 10 , 37 , 38 , 43 , 45 ) is non linear.

3 . A device according to claim 1 , comprising at least an actionable fiber ( 13 , 17 ) or a movable fiber ( 2 , 30 , 39 , 40 ).

4 . A device according to claim 3 , wherein said movable fiber ( 2 , 30 , 39 , 40 ) has at least one part ( 42 ) protruding from a channel ( 6 , 10 , 37 , 43 , 45 ) in which it is at least partly enclosed, outside of said matrix ( 5 , 36 ).

5 . A device according to claim 3 , additionally comprising means for actuation of said fiber ( 44 ).

6 . A device according to claim 1 , wherein said channel ( 6 , 10 , 37 , 38 , 43 , 45 ) is in contact either with an actionable fiber ( 13 , 17 ) or with a movable fiber ( 2 , 30 , 39 , 40 ), or wherein said channel is amenable to deformation.

7 . A device according to claim 1 , wherein the fluidic resistance of said channel ( 6 , 10 , 37 , 38 , 43 , 45 ) can be modified by the actuation of a movable fiber ( 2 , 30 , 39 , 40 ), of by a deformation of said matrix, or by a deformation of said textile ( 4 ).

8 . A device according to claim 1 , comprising at least one integrated valve, or at least one integrated pump.

9 . A device according to claim 1 , comprising an integrated window ( 24 , 25 ), in regard of at least a part of said channel ( 6 ).

10 . A device according to claim 1 , wherein the matrix ( 5 , 36 ), or the textile ( 4 ) or both have a zone of lesser resistance to deformation ( 12 ).

11 . An instrument comprising a device according to claim 1 , said instrument being any of, or any combination of, an analytical instrument, a medical instrument, a functional clothing, a wearable instrument, an implantable instrument, a monitoring instrument, a processing instrument.

12 . A method for making a fluidic device, comprising the steps of:
a/ providing a textile component ( 4 , 41 ) comprising support fibers ( 1 . 1 , 1 . 2 ) and comprising at least a movable fiber ( 2 , 30 , 39 , 40 ) said movable fiber having a multiplicity of underpasses and overpasses with at least one support fiber ( 1 . 1 , 1 . 2 ) of said textile ( 4 , 41 ), b/ embedding at least part of said textile ( 4 ) and part of said movable fiber ( 2 , 30 , 39 , 40 ) in a matrix precursor material ( 5 , 36 ), c/ applying a treatment to the matrix precursor material of step b in order to obtain a solid matrix ( 5 , 36 ), or to increase a mechanical modulus or strength of said precursor material, wherein at least part of said movable fiber ( 2 , 30 , 39 , 40 ) can move within said matrix ( 5 , 36 ) d/ moving said movable fiber at least along part of its length to create a channel embedded in said matrix, said channel being a tube or a pipe along at least part of its length.

13 . A method according to claim 12 , wherein the movable fiber ( 2 , 30 , 39 , 40 ) or movable fibers are interwoven or entangled within the support fibers ( 1 . 1 , 1 . 2 ) by the same process as used for preparing said textile ( 1 ).

14 . A method for analyzing any of a biological, a physical or a chemical agent, or for monitoring a process, environment, a living species, a condition of a patient or for producing a product, or for discovering or testing a drug or an active product, wherein said analysis, monitoring, production, discovery, or test, is performed using a device according to claim 1 .

15 . A continuous textile sheet comprising a multiplicity of distinct zones embedded in a matrix, wherein each zone comprises at least one channel embedded in said matrix and said channel having a multiplicity of underpasses and overpasses with at least some fibers of said textile component, said channel being a tube or a pipe along at least part of its length.

16 . A device according to claim 2 , comprising at least an actionable fiber ( 13 , 17 ) or a movable fiber ( 2 , 30 , 39 , 40 ).

17 . A device according to claim 4 , additionally comprising means for actuation of said fiber ( 44 ).

18 . A device according to claim 2 , wherein said channel ( 6 , 10 , 37 , 38 , 43 , 45 ) is in contact either with an actionable fiber ( 13 , 17 ) or with a movable fiber ( 2 , 30 , 39 , 40 ), or wherein said channel is amenable to deformation.

19 . A device according to claim 3 , wherein said channel ( 6 , 10 , 37 , 38 , 43 , 45 ) is in contact either with an actionable fiber ( 13 , 17 ) or with a movable fiber ( 2 , 30 , 39 , 40 ), or wherein said channel is amenable to deformation.

20 . A device according to claim 4 , wherein said channel ( 6 , 10 , 37 , 38 , 43 , 45 ) is in contact either with an actionable fiber ( 13 , 17 ) or with a movable fiber ( 2 , 30 , 39 , 40 ), or wherein said channel is amenable to deformation.
