Developed in the UK, the new machine detects the breath and sweat of survivors trapped in rubble. It's better than sniffer dogs, and could reduce the risk to them. From the article: 'The sensor technology was shown to accurately detect human-generated carbon dioxide and ammonia in air that wafted through gaps in the rubble during testing, something that previously only dogs could do, as other technologies focus more heavily on seeing or hearing a survivor.'"
