Knitted textile substrate with different stitch patterns and electronic textile
A knitted substrate ( 4; 16 ) for electrical connection of electronic components ( 3; 17 a - f ) thereto. The knitted substrate comprises a first set of substrate portions ( 5 a - e; 9 a - f ) knitted with a first stitch pattern resulting in a first tensile stiffness; and a second set of substrate portions ( 6 a - f; 18 a - f ) knitted with a second stitch pattern resulting in a second tensile stiffness that is greater than the first tensile stiffness. A substrate portion of the first set of substrate portions ( 5 a - e; 19 a - f ) is provided between substrate portions ( 6 a - f; 18 a - f ) of the second set of substrate portions, and each substrate portion of the second set of substrate portions ( 6 a - f; 18 a - f ) comprises conductive yarns ( 11 a - b ) arranged to allow electrical connection of at least one of the electronic components ( 3; 17 a - f ) thereto.
1. A knitted substrate for electrical connection of electronic components thereto, comprising:
conductive yarns and non-conductive yarns;
a first set of substrate portions knitted with a first stitch pattern of said non-conductive yarns, resulting in a first tensile stiffness; and
a second set of substrate portions knitted with a second stitch pattern of said non-conductive yarns, resulting in a second tensile stiffness that is greater than said first tensile stiffness,
wherein a member of said first set of substrate portions is provided between members of said second set of substrate portions, and
wherein each member of said second set of substrate portions comprises conductive yarns arranged to allow electrical connection of at least one of said electronic components thereto.
2. The knitted substrate according to claim 1 , wherein said members of said second set of substrate portions are knitted from said conductive yarns and non-conductive yarns.
3. The knitted substrate according to claim 1 , wherein said member of said first set of substrate portions being provided between members of said second set of substrate portions is rib-knitted.
4. The knitted substrate according to claim 1 , wherein at least one of said members of said second set of substrate portions is knitted in a stockinette pattern.
5. The knitted substrate according to claim 1 , wherein said members of said first set of substrate portions and members of said second set of substrate portions are arranged in alternating stripes.
6. The knitted substrate according to claim 1 , wherein said members of said second set of substrate portions are arranged as islands, each being substantially surrounded by an associated member of said first set of substrate portions.
7. An electronic textile comprising:
the knitted substrate according to claim 1 ; and
a plurality of electronic components, each being attached to a member of said second set of substrate portions comprised in the knitted substrate in such a way that said electronic component is electrically connected to at least one conductive yarn.
8. The knitted substrate according to claim 1 ,
wherein said first set of substrate portions does not share a common member with said second set of substrate portions.
