Experiment with paper electronics with this silver conductive ink pen that will let you draw traces! We like the make of this pen, it has a nice liquid silver ink that flows easily, and it works great. In just 3 minutes from opening the packaging, we made the image above, a coin cell holder with an LED.
There are two ‘tips’ available — standard and micro. The microtip allows for finer control but is a little harder to use (because it doesn’t deposit as much silver at once).The CW2200STP (standard tip pen) has an orifice size of 1 mm and will draw traces that will average 2.0 mm in width. The CW2200MTP (micro-tip pen) has an orifice size of 0.7 mm and will draw traces that average 1.5 mm in width. See the image above with a demonstration of the kind of traces you can draw with each of the lines (by someone with no practice
We strongly suggest reading the excellent tutorial document written by the makers which discusses use, shelf life, safety, soldering, and more!
