  • Publication number: 20220015228
    Abstract: A substrate that is stretchable and that at least has a wiring region; wiring at least positioned in the wiring region on a first surface side of the substrate, the wiring having a meandering shape section that includes peaks and valleys aligned along a first direction that is one of planar directions of the first surface of the substrate; and a stretching control mechanism that controls extension and contraction of the substrate. The stretching control mechanism at least includes stretching control parts that are positioned in the wiring region of the substrate and that are aligned along the first direction.

  • Publication number: 20220015227
    Abstract: A wiring board on which electronic components are mountable includes a stretchable portion having stretchability and having a first surface and a second surface opposite to the first surface, and an interconnection wire electrically connected to the electronic components mounted on the wiring board. The stretchable portion includes first regions lined up in each of a first direction and a second direction, a second region including first portions and second portions, and a third region surrounded by the second region. The first regions overlap the electronic components. The first portion extends from one of two first regions neighboring each other in the first direction to the other thereof. The second portion extends from one of two first regions neighboring each other in the second direction to the other thereof. The second region has a lower modulus of elasticity than the first region. The interconnection wire overlaps the second region.

  • Publication number: 20210410280
    Abstract: A wiring board includes a first substrate having stretchability, wiring disposed adjacent to a first surface of the first substrate and extending in a first direction, and a stopper disposed adjacent to the first surface or second surface of the first substrate. While stretch length of the wiring board is being increased in the first direction, electrical resistance of the wiring exhibits a first turning point at a first stretch length and tension applied to the wiring board exhibits a second turning point at a second stretch length smaller than the first stretch length. The first turning point is a point at which an increase in electrical resistance per unit stretch length changes. The second turning point is a point at which an increase in tension per unit stretch length changes.

  • Publication number: 20210385946
    Abstract: A wiring board includes a substrate, wiring, and a reinforcing part. The substrate is stretchable, and includes a first surface and a second surface located opposite to the first surface. The wiring is located at the first surface side of the substrate. The reinforcing part overlaps the wiring when viewed in a direction normal to the first surface of the substrate. The substrate has a control region and a non-control region. The control region overlaps the reinforcing part. The non-control region does not overlap the reinforcing part. The non-control region is positioned to sandwich the control region in a direction orthogonal to the direction in which the wiring extends.
