The eye-strain implications alone are staggering.
To promote the upcoming Exceptional Hardware Software Meeting (EHSM) in Hamburg, Germany, a team of DIY artists and scientists has etched the world’s smallest comic strip on a single human hair.
Titled “Juana Knits The Planet,” the strip was created by German artist Claudia Puhlfurst, then carved into the hair using a process called focused ion beam (FIB) etching. “A very sharp and high-speed jet of matter is produced and directed towards the hair to etch it — similar to a fine laser beam,” according to the project’s YouTube page.
Each of the strip’s 12 frames measures in at around 25 micrometers. A micrometer, or micron, is one millionth of a meter. A typical human hair is anywhere from 20 to 200 microns in width.
The second annual EHSM event bills itself as a meeting of international makers, hackers, scientists and engineers aiming to deliver on the “third industrial revolution.” The rest of the conference looks pretty trippy, too.
Among the presentations: electron beam welding, quantum cryptography and the interesting things that happen when molten glass, heated to 1,260 degrees Celcius, hits water. I’ve always been curious about that.
