  "textContent": "Researchers have developed a simple and eco-friendly way to use a laser to turn natural leather into flexible and wearable energy devices. The new approach could lay the groundwork for more sustainable wearable electronics. In a paper in Optics Letters, the researchers demonstrate the new technique by creating microsupercapacitors on leather in various patterns, including a tiger, dragon and rabbit.",
