We've already heard about conductive inks that allow electrical circuits to be hand-drawn onto materials, using a ballpoint pen. Scientists have now developed a new such ink, which they claim is ...

Conductive ink has been around for a while and is a tool for printing flexible electronic circuits on various surfaces. One challenge with current conductive ink is that the ink can be expensive and ...

Conductive ink is a great tool for printing flexible electronic circuits on surfaces. But these inks can be costly, they do not work on some materials, and devices to apply them can plug up. Now, ...

I checked a bunch of "maker" type stores, like SparkFun, Adafruit, MakerShed, etc. SparkFun and MakerShed had a water-soluble trace pen, but that didn't sound very ...
