Self-powered fibers can spot oil contamination and heat buildup within milliseconds

Oil spills and fires are two very different hazards, but both can cause major damage before people have time to react. Oil contamination can spread quickly across water and harm marine ecosystems, while undetected heat buildup can lead to destructive fires in high-risk environments. Many current warning systems depend on batteries, large instruments, or delayed responses, making early action difficult in remote or demanding conditions.
