Abstract
Official abstract text for this publication.
Provided is a stretchable circuit board including a stretchable insulating layer, and a wiring, in which the wiring is formed of a combination of a metal wiring portion that forms a main portion of the wiring, and a conductive stretchable portion disposed ancillary to the metal wiring portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A stretchable circuit board, comprising: a stretchable insulating layer configured to be stretched in a longitudinal direction; and a wiring that is formed of a combination of: a metal wiring portion that forms a main portion of the wiring and an electrically conductive stretchable portion disposed ancillary to the metal wiring portion, wherein the metal wiring portion is defined by a linear or curvilinear form that extends between and includes opposing ends of the metal wiring portion that are spaced apart in the longitudinal direction, and wherein the stretchable insulating layer has a first surface and a second surface that opposes the first surface, the wiring is formed on the first surface and the second surface, and a bridging portion that extends between the wiring formed on the first surface of the stretchable insulating layer and the wiring formed on the second surface of the stretchable insulating layer is formed of the electrically conductive stretchable portion. 2. The stretchable circuit board according to claim 1 , wherein the wiring is a meander wiring. 3. The stretchable circuit board according to claim 1 , further comprising a pad portion, wherein a connection portion between the wiring and the pad portion is formed of the electrically conductive stretchable portion disposed ancillary to the connection portion. 4. The stretchable circuit board according to claim 1 , further comprising a pad portion, wherein the pad portion includes a metal layer forming a main portion of the pad portion, and the electrically conductive stretchable portion disposed ancillary to the metal layer. 5. The stretchable circuit board according to claim 1 , wherein the electrically conductive stretchable portion is formed by using a conductive composition or a liquid metal. 6. A stretchable circuit board, comprising: a stretchable insulating layer; a wiring that is formed of a combination of: a metal wiring portion that forms a main portion of the wiring and an electrically conductive stretchable portion disposed ancillary to the metal wiring portion; and a pad portion, wherein a connection portion between the wiring and the pad portion is formed of the conductive stretchable portion disposed ancillary to the connection portion, and wherein the stretchable insulating layer has a first surface and a second surface that opposes the first surface, the wiring is formed on the first surface and the second surface, and a bridging portion that extends between the wiring formed on the first surface of the stretchable insulating layer and the wiring formed on the second surface of the stretchable insulating layer is formed of the electrically conductive stretchable portion. 7. A stretchable circuit board, comprising: a stretchable insulating layer; a wiring that is formed of a combination of: a metal wiring portion that forms a main portion of the wiring and an electrically conductive stretchable portion disposed ancillary to the metal wiring portion; and a pad portion, wherein the pad portion includes a metal layer forming a main portion of the pad portion, and the conductive stretchable portion disposed ancillary to the metal layer, and wherein the stretchable insulating layer has a first surface and a second surface that opposes the first surface, the wiring is formed on the first surface and the second surface, and a bridging portion that extends between the wiring formed on the first surface of the stretchable insulating layer and the wiring formed on the second surface of the stretchable insulating layer is formed of the electrically conductive stretchable portion.
