| 摘要 |
<p>A cable 2 has an outer sheath on which a layer of selectively activatable material such as a layer of thick-film conductive polymer is sprayed to form a resistive element. A layer of thermochromic ink is printed on top of this. Electric current passed through the resistive element provides heating to the ink and causes it to warm and change colour. <IMAGE></p> |
