Don't wire a circuit—doodle it. To connect batteries to devices such as resistors and LEDs, a newly developed ballpoint pen uses silver-based ink that conducts electricity through lines drawn over paper, wood, plastic and even some textiles. Jennifer Lewis, the materials scientist who led the pen's design at the University of Illinois, says she is now looking for business partners and hopes to have products that integrate the pen and ink on the market within a few months. Check out video of the ink below!
How is this invention "NEW"? There are already conductive inks commercially available.
Maybe if you watch the whole video, you would know. Starting at 1:00, she tells you whats different between her pen and other commercially available pens.
sooooooo can i draw my own computer with this? cause that would be sick
I learn something new every day but not here. Last week I learned that pencil graphite is not only conductive, but offers enough resistance to be its own resistor. Thanks Science Tuesdays! As far as I know pencils have been around for a little while now. What makes this conductive ink special? Is it the level of conductivity?
what would really make this a great product is if it was made into printer ink with an accompanying program that let you draw circuits on your computer and just print them out on sticky paper so you can stick it on to any blank pcb board and have a testable pcb in a matter of minutes. That would make this ink truly useful. btw if you steal this idea you better cut me in. haha ;)
then again you could just draw on the pcb
I tend to agree with JohnWa. The headline would be better if it read "improved conductive ink". It's a refinement, not a new concept.
best friend's aunt earned $21577 the previous month. she is making an income on the internet and moved in a $456100 house. All she did was get blessed and put to work the information shown on this web site urlgator.com/yn9Xf
I have a conductive ink pen, this version does look marginally better but there are some things to consider.
A product will need to be able to withstand many hours of vibration on trucks storage for years in warehouses and store shelf's and not separate in freezing - thawing conditions. Another huge consideration is the cost, you can probably sell it for $20 but your retailer is going to want 40% and the distributes will need 20% so you will have to produce it for less than $10 and silver is not a cheap metal.
But I don't think she cares much about turning it into a product, if she did she would not be showing the world precisely how its made.
deja vu posting, lol.
Well, the conductive ink pen is very cool.
Science sees no further than what it can sense, i.e. facts.
Religion sees beyond the senses, i.e. faith.
Open your mind and see!
I really like the idea. What would make it cooler is if other ink like components are made to compliment it. Let's say luminescent-ink (ink that lights up when electricity passes through it), Resistor based ink( would already have some relevance to the ink already made). If you could create transistor based ink, that would be infinitely awesome. Can't wait to see what comes next^_^...
@adaptation "But I don't think she cares much about turning it into a product, if she did she would not be showing the world precisely how its made."
I don't think she is too worried about losing that portion of her potential market that have heated sonic baths, centrifuges and know where to get each of those chemicals. Granted, conductive ink is kind of a niche tech thing anyway but those still aren't exactly standard tools in the average electronics workshop, home or commercial.
Besides, if she is patenting this process (I don't know, is she?) then it becomes public knowledge anyway.
Have a look at this
is a possible engine made from a naturally occurring high crystalline high diamagnetic graphite and then have a look at this
it is for a conductive ink that’s makes the competition look like pants.
You can get these things really easily from
for the ink and diamagnetic graphite. And they are cheap!
