What if your sketch of a circuit could function as a circuit? With conductive ink, it can.
In this video graduate students from the University of Illinois demonstrate how to create conductive and easy flowing silver ink, perfect for drawing functional electronic circuits. From the video description:
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.
Check out the video above to not just see it in action but watch the entire creation process from start to finish.
