Researchers at the University of California San Diego have designed an electronic tattoo—a small, flexible circuit board that can be worn just like the Spiderman temp tats I used to stick on my face—that produces an electrical current.
It works by stripping the electrons from lactate, a byproduct of sweat, with an enzyme imprinted on the e-tattoo’s sensor. In other words, it produces power from your nasty workout juice. And, the researchers say, the technology could eventually generate enough electricity to run devices like phones, smart watches, and heart monitors.
"These represent the first examples of epidermal electrochemical biosensing and biofuel cells that could potentially be used for a wide range of future applications," said research lab director Joseph Wang in a statement.
