Virginia Tech Engineers Craft Durable, Self‑Repairing, and Recyclable PCBs

Scientists have developed a self-healing, recyclable circuit board using vitrimer and liquid metal. The material maintains conductivity after damage, reshapes under heat, and may reduce growing e-waste. Unlike traditional boards, it allows easy repair and recovery of materials, offering a sustainable solution for electronics like smartphones, laptops, and wearables, a...
