World records have tumbled and gold medals won but the colourful array of tattoos on show at the world swimming championships have proved just as eye-catching, be they designs of sharks, dolphins or even the lion adorning the arm of Adam Peaty’s grandmother.
A vast array of images, script, and secretive symbols adorned the bodies of competitors, from flowing and harmonious waves to powerful and speedy creatures of the deep.
The Olympic rings — a proud stamp on the skin of the swimmers who competed at a Games — are also common place, but some of the world’s fastest have explained the thinking behind the art work on their bodies.
“Temporary tattoos aren’t just for style anymore,” said Aneri Pattani at The New York Times. Japanese scientists have developed a wearable sensor that can monitor patients’ vital signs, and also “looks and feels like a henna tattoo.” That’s a big advantage over current devices made out of polyester or rubber sheets that aren’t breathable enough to allow air to pass through, making the wearer sweaty and itchy.
