A researcher from the University of Leeds, with European quality funding, offers creative solutions to deal with the damage to the body and structures caused by the earthquakes

A project headed by Prof. Terry Wilkins (Wilkins) from the University of Leeds, UK, funded by the European Union, raises hope for a better deal with the damage to the body and the damage to the buildings caused by earthquakes. The project, called ISSB (the acronym for Intelligent Safe and Secure Buildings - sophisticated, safe and secure buildings), offers to deal with the problem in four ways.
One way is through the development of a polymeric material that will turn into a liquid when a certain amount of pressure is applied to it, and harden and become a solid when the pressure is removed. The material will be added to the other building materials from which the safety buildings will be built. During an earthquake, pressure will be applied to the structure, and as a result, the polymer will turn from a solid to a liquid. The liquid will flow into the cracks that will form in the building during the earthquake, will become solid again and thus will unite the building.
The second way is through the distribution of an "intelligent" network of sensors, which will communicate with each other wirelessly. The sensor network will be embedded inside the building. It will constantly collect information on phenomena that may adversely affect the structure, such as pressures, fluctuations, changes in temperature and humidity, and more. When an earthquake is approaching (which the sensors will notice even before the occupants of the house), the system will be able to warn of the approach of the earthquake and thus give the residents of the house a period of time to evacuate themselves from it. Since the sensor network will be able to measure a variety of types of information relevant to the condition of the building, it will be able to warn not only of an upcoming earthquake, but also of other phenomena that could damage the building and possibly lead to its collapse or disintegration.
The third way focuses on the possibility of the building collapsing - if finally the worst happens and the building collapses, the sensor network embedded in the building will be able to provide information about the condition of the people trapped inside it and their location. This information will be able to assist in rescue operations.
The fourth way focuses on the investigation after the fact - the information gathered by the sensor network can be used to investigate the reasons that caused the collapse of the building, something that can help draw conclusions and provide recommendations to prevent or reduce damage in the future.
The project managers aim to build a prototype of the warning structure with the ability to self-repair in the town of Amphilochia in Greece, by December 2010. If the mechanisms that will be installed in it work as expected, it will be possible to move forward with the construction of this type of building on a large scale.

It sounds strange because there are already structural solutions for earthquakes that have proven themselves... and here they want to develop a polymeric material, which means the material does not yet exist and it is not certain that it can be developed!! And it sounds quite unnecessary!
Regarding the sensors ..I didn't know that the European Union pays for initial ideas (only because universities sign them?) !!
It reminded me of my idea after the fall of the twins of attaching a transmitter or sensor to each person in large buildings that would also include details about their subject of course to facilitate the search for survivors in the building and if the system works well... even knowing how many are trapped!! Who are they and their location in the ruins and maybe even if they are alive and thus direct the searchers towards life first!! Will I be paid for this??
It also reminded me of the beginning of my new path in 88-9 I "planned" in my mind and on a page a bridge that would connect between the Arab Republic of Israel and the Federal Republic of Israel a distance of 180 km in the air, with the middle of it rising to a height of 30 km (two halves of a triangle) not for execution But as an exercise to develop thinking!!
I decided on the development of a single constructive "brick" made of iron pipes (as iron beams are built) with joints to connect the units. I expected neither 21 nor 12!! And here is the link to the article.. I was then thinking about embedding sensors in each unit to automatically stabilize the bridge and actually turn it into a living body! By the way, the size of the unit was supposed to be around 16 cm.. it's big because of the huge size of the building in other buildings it can be reduced up to 90 cm let's say! The units were supposed to connect independently after bringing them closer to a certain distance (this is good for building buildings in space, to be honest) and other things that required solutions... I really enjoyed it! Unfortunately "unfortunately" three years later Barhem fell and the Peace Bridge is no longer needed!!
Where do you pay?? Does anyone know? (jokingly??)
you know what? I didn't take myself seriously until Yamaha produced a product I designed!! And this time I also bothered to go to the product development company, I showed them the automatic hair clipper, but I did not agree to pay $500 to have them prepare a thick book promoting the product (and I was wrong by the way!) After about 4 years, Yamaha offered such a product. They have the idea .. it's good because it means that there really is something in what I thought and not just !!
Last Saturday my cell phone was stolen in the Birkon in the middle of the day..I think it is a big Russian cyclist (be careful!) and this is the second cell phone in a year!! The insult was severe and I sat down to think about what I was doing...at first I came up with the idea of electronic protection that would alert me (something that would have prevented both thefts in my case). These systems in electronic systems that will make it very, very difficult to steal all the products and will leave the courts and the police without employment!!
The question, as usual, is where my head will be on Sunday! That's how hundreds and more ideas went to them along the way, every idea I have.. deep in the closet .. close to 15 years of zero implementation.. amazing !!
Maybe this time I will catch stubbornness and lack of giving up on myself until the task is completed or at least its beginning!!
Aggie needs a contact person for big electronics companies like Sony and similar...I think this is the future!! Because the thieves are also tired of disgusting bicycle thieves or those who dismantle them, especially the seat... Thieves, you are tired and you will get a real war.
It actually seems to me that such a substance, which becomes liquid under pressure, will destabilize the buildings during an earthquake and cause them to collapse. In addition, if after the collapse, this material hardens, it will make it difficult to remove the crushed concrete blocks, and save those buried under it.
It is known that sand containing little water, on which buildings are built, becomes liquid during an earthquake, and the building built on it sinks or collapses.
Regarding the sensor system to warn me of earthquakes, it is a good idea but it can be attached to the walls externally and not inside the construction.

It wouldn't be easier to make a mixture that hardens on it
pressure?
