A better pen-and-ink system for drawing flexible circuits
E-Mail IMAGE: A pen containing conductive ink can draw circuits on a variety of surfaces -- even a loofah (seen here). view more Credit: Adapted from 2020, DOI: 10.1021/acsaelm.0c00866 Conductive ink is a great tool for printing flexible electronic circuits on surfaces. But these inks can be costly, they do not work on some materials, and devices to apply them can plug up. Now, scientists report in ACS Applied Electronic Materials that they have developed inexpensive conductive inks for clog-free ballpoint pens that can allow users to "write" circuits almost anywhere -- even on ...
