Smart Bricks to Monitor Buildings of the Future 142

Roland Piquepaille writes "Scientists from the University of Illinois at Urbana-Champaign have developed a "smart brick" which can monitor a building's health and report its conditions wirelessly. "This innovation could change the face of the construction industry," said Chang Liu, a professor of electrical and computer engineering at Illinois. "We are living with more and more smart electronics all around us, but we still live and work in fairly dumb buildings. By making our buildings smarter, we can improve both our comfort and safety." Built into a wall, these bricks could monitor a building's temperature, vibration and movement. Such information could be vital to firefighters battling a blazing skyscraper, or to rescue workers ascertaining the soundness of an earthquake-damaged structure. These researchers also think these devices could help monitoring nurseries, daycares and senior homes. You'll find more details in this summary."

    This could be a very expensive and useless technology. The proposal for it and the quote by the professor who apparently invented it are reflective of the brick's function as more of a "black box", as in an airplane, rather than a useful tool. If the brick says the buildings about to fall, what can the owners do? The excuse that it helps firefighters is totally ridiculous, firefighters aren't going to have time to jack in to a network plug when they're trying to save lives.

      If the brick says the buildings about to fall, what can the owners do?

      I think the idea would be to detect movement of the brick relative to other parts of the building. This would allow the owner to detect and have the opportunity to correct any structural problems well before the building is in any danger of collapse.

      The excuse that it helps firefighters is totally ridiculous, firefighters aren't going to have time to jack in to a network plug when they're trying to save lives.

      Remember, not everybody who works for a fire department rushes into burning buildings to save people. Some people at the scene are going to set up a command center. Presumably, the command center would be equipped to monitor such 'smart' building materials and relay important information to firefighters in the building.

      The other touted use it to sense vibrations. I don't know about you, but I know when there's an earthquake and when there's not, I don't need a brick to tell me.

      After a major earthquake occurs, buildings need to be inspected to determine how much structrual damage has occured. Knowing the magnitude and direction of the vibrations sensed at various parts of the building could help the damage assessment process.
      • Your assertions are currently well enough covered by good old expertise and shoe leather. Buildings tend to already have inspection systems known as superintendents, or facilities departments with workers and a manager. Cheaper and more reliable options for inspection can and ARE being fulfilled with periodic Human involvement and sensors. This would still be the case with so-called automated sensors ... as you well know, data doesn't inspect itself; somebody has to look at it.

    The problem with technologies like these are that they're simply form factor adjustments of existing technologies.

    Currently you can very easily put temperature sensors (or even seismic detectors) in a building, but this project wants to put these items into a brick with a wireless connection. Is this really a story? Sure, such a brick might exist in every new building in the future, but you could have this in your home right now, in a small box containing the same gadgets. Putting it in a brick just doesn't seem that exiting, y'know?

    Built into a wall, these bricks could monitor a building's temperature, vibration and movement.

    ...and built into a wall, there's no way to fix the 'brick' when it breaks down and stops working. All of the above functions can be performed by sensors ON the wall,floor, ceiling, etc- or post-construction inside the wall, accessible via an access panel. Or you can make a brick that's not completely 'built in'- ie, you make a place for it, a box or something- and the sensor can still be serviced, you still get advantages of easy installation, etc.

    So maybe you put a slew of them in-I suppose ease of installation counters the increased cost of deploying more of them. But still, that's great- now you've raised the chances that one of them will fail(since there are more of them)...and they're possibly more unreliable, and accuracy or precision will be worse since, well, you made 'em cheaper.

    If you look at the vibrations coming out of a building that is burning there is a huge jump in the amplitude of certain bands right before the building collapses.. there's basically a shift in the fundamental frequency of the building. A brick to detect this is gonna save alot of firefighters.

    Basically, any structure like a bridge or a building can be characterized pretty well by its frequency response. You stimulate it with an impulse and transform the output to the frequency domain. A burning building is being constantly stimulated, so detecting the vibrations with a brick in the wall is going to let you easily determine the frequency response.

    As you can imagine (this is a generalization) if there's a large spike in certain frequencies, the structure is unstable. When you engineer structures, you try and keep the frequency response flat.

    What are the odds that, 50 years from the time the bricks are installed, the technology will still be around to access the data from the brick? The information will probably be most useful once the building really starts to decay -- if this technology had been around 50 years in the past, we'd all still need room-sized mainframes in order to access the data our buildings are providing us -- or, failing that, we'd need to rip out all the smart bricks and upgrade them with new ones.
