Researchers develop fully biodegradable robotic finger

Researchers have created a breakthrough robotic finger that completely biodegrades after use, addressing the growing electronic waste crisis that reached 62 million metric tons in 2022. The finger uses polyglycerol sebacate rubber and twenty-one electronic components made from naturally degrading elements like magnesium and silicon, maintaining full functionality through over one million bending cycles. When composted, the entire system decomposed within months, with the resulting soil successfully growing oat plants, proving its eco-safety.
