Valuable paintings that are shipped or loaned to museums or other destinations around the world will soon have unusual traveling companions for their long journeys – sensors that can detect the buildup of pollutants within their specially-designed shipping crates. Occasionally, adhesives and other chemicals within the crates can breakdown and the fumes can damage the works of art. But the new sensors, developed by scientists at the Fraunhofer Institute for Silicate Research ISC in Würzburg, Germany, will detect these dangerous substances and help avoid the treasures being damaged.
