Scientists design smart paper capable of detecting water, conducting electricity

Nov. 7 (UPI) -- Scientists at the University of Washington have designed smart paper capable of sensing water and conducting electricity. The paper could be used to detect water leaks in city pipes.Even small leaks in a city's maze of pipes can prove costly. Left alone, the problem can get worse. And finding the leak can prove timely. The American Water Works Association estimate leaks cause 250,000 water line breaks every year, costing public water utilities an annual sum of $ 2.8 billion.Scientists hope their new smart paper can shrink those costs by making it easier to find and fix leaks.The paper can sense the presence of water and conduct an electric current to sound an alarm or trigger a light, alerting maintenance authorities to the presence of a leak."Water sensing is very challeng...
