Abstract
The present invention provides to a wearable smart device having electrical wiring comprising a stretchable conductive composition having excellent in durability such as repeated bending properties and repeated twisting properties, a material for realizing the wearable smart device, and a method for producing the wearable start device.An electrical wiring including a fine line having an electrical line interval of 1 mm or less, preferably the line width of less than 1 mm, is formed by printing a paste for forming a stretchable conductor containing metal-based conductive particles and a non-crosslinked elastomer, and further dried and cured at a low temperature condition of 120° C. for 30 minutes. As a result, the wearable smart device having electrical wiring constituted by fine lines without sagging of the edge is obtained.
