HOW TO – Conductive Silver Ink from a Ballpoint Pen

HOW-TO – Conductive Silver Ink from a Ballpoint Pen via BB

Materials researchers at the University of Illinois, Urbana-Champaign have developed a highly conductive silver ink. In this video, Analisa Russo, a graduate student in the research group of Professor Jennifer Lewis shows exactly how to make this amazing ink, which could be used for a wide variety of hobby projects and in advanced electronics hardware.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. This is SO Cool! This would be fun to show at my club I do at school!
    Thanks for sharing 🙂

  2. OK, very impressive in a ballpoint but I’m assuming everyone else is thinking inkjet too?

  3. Looks like the Reprap just got a new head!
    Materials engineering represent.

  4. Nice! The lab equipment puts it out of reach for the rapidly proliferating makerus onabudgeta, which is known more commonly as a Frugal Maker.

  5. @ransomhall: Agreed, but if someone took on the makerus penlabus mantle, I’d expect to see a proliferation of makerus buyacouplea.

  6. I’m throwing my money at the screen but nothing is happening…
