Japanese Company, AgIC, have recently come to our attention with their development of a Circuit Marker Pen.
With the look and feel of a typical marker pen, the Circuit Marker Pen contains silver conductive ink which dries within a few seconds and becomes conductive almost instantly; when coupled with AgIC's Circuit Paper, circuits to power LEDs or motors can be drawn.
AgIC's mission is to make electric circuits more accessible to people of all ages and levels of experience.
Based in Tokyo, AgIC began as a start-up in 2014, and have since developed several conductive products. We look forward to seeing more from AgIC in the future.
