A villa designed to resist earthquakes by ‘self-healing’ cracks in its own walls and monitoring vibrations through an intelligent sensor network is to be built on a Greek mountainside.
The University of Leeds’ NanoManufacturing Institute (NMI) will develop walls for the house that contain nano polymer particles under the £9.5m EU-funded project. These will turn into a liquid when squeezed under pressure, flow into the cracks, and then harden to form a solid material.
NMI chief executive Prof. 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.’
The house walls will be built from novel load bearing steel frames and high-strength gypsum board. They will 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,’ added Prof. Wilkins.
The Leeds team also includes Dr Roger Gregory, chairman of University spinout company Instrumentel, who said: ‘Leeds are world leaders in designing wireless networks for extreme environments and hard-to-access places. Even if the building totally collapsed, the sensors would still let you pinpoint the source of the fault.’
Instrumentel will work in partnership with Dr Greg Horler in the School of Electrical and Electronic Engineering to deliver this potentially life-saving technology.
Meanwhile, Prof. Anne Neville’s team in the School of Mechanical Engineering will research new ways of designing the polymer nano-particles required.
Prof. Wilkins said: ‘Once we have the optimum design, we could quickly start producing thousands of litres of nanoparticle fluid, adding just a tiny percentage to the gypsum mix.’
Leeds will join 25 other partners in the project, led by the German building manufacturer Knauf. Due to be completed in December 2010, the work is worth around £980,000 to Leeds.
