Using this ITO - coated PET plastic is easy and fun. First, if you want to create 'traces', you can take a flat - edged blade and gently scrape off some of the ITO film on the coated side. You can also experiment with a laser cutter to make different patterns. When it comes to making electrical contact, forget about soldering. Instead, use conductive inks, paints, copper tape with conductive adhesive, or alligator clips. As for maintenance, keep it in a dry place at normal room temperature. Avoid bending it too sharply as it may damage the ITO coating. That's it! Have a great time exploring with this awesome material.
