Question

A villa (别墅) designed to resist earthquakes with “self-healing” cracks in its walls thanks to nanotechnology (纳米技术) applications with self-healing polymers (聚合物) is to be built on a Greek mountainside. The villa’s walls will include special particles that turn into a liquid when squeezed (压榨) under pressure flow into cracks and then harden to form a solid material.

The NanoManufacturing Institute (NMI) based in Leeds University will play a key role in an EU project to construct the home by December 2010. The project called “Intelligent Safe and Secure Buildings” (ISSB) is funded under the EU’s Sixth Framework program. This potentially life-saving scheme is led by German building manufacturer Knauf. The villa will be built in Amphilochia in western Greece where Knauf currently runs a manufacturing plant. If the experiment is successful more tremor-resistant（防震）homes could be built in earthquake zones across the globe. NMI chief executive Professor Terry Wilkins said “What we’re trying to achieve here is very exciting. We’re looking to use polymers in much tougher situations than ever before on a larger scale.” Monitors contained in the villa’s walls will be able to collect vast amounts of data about the building over time. Wireless sensors will record any stresses and vibrations as well as temperature humidity and gas levels.

The walls are to be built from new load-bearing steel frames and high-strength gypsum（石膏）board. Prof Wilkins said “If there are any problems the intelligent sensor network will be able to alert residents immediately so they have time to escape.” If whole groups of houses are so constructed we could use a larger network of sensors to get even more information. “If the house falls down we have got hand-held devices that can be used over the rubble to pick out where the embedded（嵌入的）sensors are hidden to get some information about how the villa collapsed.” Also we can get information about anyone who may be around so it potentially becomes a tool for rescue.
