Abstract
A stretchable structure comprises or is configured to receive a conductive path and an interface region. The interface region comprises a peripheral line comprising at least one inwardly curved portion, such as an “inverted teardrop” or a fjord like recess pointing essentially towards the center area of the interface region. The interface region is arranged to receive said stretchable conductive path via said inwardly curved portion of said peripheral line of said interface region. In this way the interface region minimizes strains or other twisting or stretching forces directed to the conductor entering into the opening of the inwardly curved portion of the interface region.
