Smart liquid goes dark in the heat

A smart liquid that darkens dramatically in response to rising temperature has been developed by researchers at A*STAR. The nanowire-based thermochromic liquid's tunable color-changing behavior was retained even after hundreds of heat-cool cycles. This liquid could have applications ranging from smart windows to paper-based temperature sensors, the researchers say.
