This temporary tattoo can monitor your vital signs

This is really cool

A temporary tattoo that monitors vital signs.

"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.
