Feel Like Drawing Circuits? [Video]

A company in Tokyo, AgIC, developed a circuit marker pen with a silver-based conductive ink that dries and becomes conductive immediately on circuit paper. And an eraser removes traces of the ink. Because the circuits are made on paper, folding is possible as long as it doesn’t break the circuits. Flexible circuits can be printed by using the special ink in home inkjet printers. The company also offers prototyping and industrial applications.
