It appears to handle reasonable amounts of current, it can drive an LED over about 10" of trace in the LED grid example. That example also has cross overs, though they don't mention it in the article.
I wonder how they bond the components to the traces. Is setting them on fresh ink sufficient?
- delinka 15y agoBinding components to the traces (or even keeping them on the paper) is definitely my biggest area of curiosity. Putting a lil-dab-o-glue on the bottom would certainly be problematic as it would spread to insulate the connections. Components with adhesive surfaces would solve the problem of sticking it to the paper but not the problem of binding to the trace path. I have no ideas how that would work.
- ajdecon 15y agoI used to work in the lab in question, though nowhere near this project. (And I'm ridiculously proud of my colleagues right now. :D ) To answer your question, setting the components on fresh ink is often sufficient but not always. IIRC, components were often put in place and then "drawn over" a second time with the pen, or small beads of ink were put in place. I saw cross-overs demonstrated simply using normal white-out (!) after the first trace was dry, but I no longer have access to a journal subscription so I'll have to bug my colleagues for a copy before I know if that is what was used in the publication.
