Self-healing villa repairs cracks and monitors vibrations

from Around The Home (319 articles)

May 12, 2007 A US$18.6 million “self-healing” house will be able to resist earthquakes by sealing cracks in its walls and monitoring seismic vibrations. The walls of the house contain nano polymer particles designed to convert into liquid when under pressure, flow into cracks, and solidify. This would theoretically stabilize the structure after severe seismic trauma. Funded by the European Union, and using technology from Leed University’s NanoManufacturing Institute, the house is to be constructed in Greece by 2010.

The house walls will be built from novel load bearing steel frames and high-strength gypsum board. But they will also contain wireless, battery-less sensors and Leeds-designed radio frequency identity tags that collect vast amounts of data about the building over time, such as any stresses and vibrations, temperature, humidity and gas levels. “If there are any problems, the intelligent sensor network will alert residents straightaway so they have time to escape,” stated Professor Wilkins, of the NMI. Dr Robert Gregory of Leeds added “Even if the building totally collapsed, the sensors would still let you pinpoint the source of the fault.”...
