IEC 62899-202-4:2021(E) defines the terminology and measurement methods for the properties of stretchable printed layers, such as conductive ink, for forming stretchable conductors by printing, stretchable conductive films obtained from conductive ink, and stretchable printed wiring consisted by conductive ink with insulator.
Stretchable printed layers (conductive and insulating) handled by this document apply to the stretchable electric wiring printed on stretchable substrates, for example fabric integrated wearable devices, skin patchable devices, and so on.
