The new piezoelectric fabric hears the sound of the heart.

(An MIT team has designed an “acoustic fabric,” woven with a fiber that is designed from a “piezoelectric” material that produces an electrical signal when bent or mechanically deformed, providing a means for the fabric to convert sound vibrations into electrical signals.

Piezoelectric nanotechnology is not a new thing. There is made research with fabric and clothes that can recharge mobile telephones. The idea of those systems is that the body movements can change to electricity by using piezoelectric fabric. But the same style of piezoelectric fibers can use as the fabric that can hear the heart. Or it can use as a microphone that can transform the resonance of layers to electric impulse and sound.

The new acoustic fabric is made by using piezoelectric material. That material allows the fabric to hear the sound of the heart. And this thing makes it possible to create new intelligent clothes that are observing the condition of humans or animals. The clothes that are made by using this intelligent material can connect to the wristwatch-size computer that resends the biometric data to the mobile telephone. And the mobile telephone can communicate with any computer in the world.

But the same system can use as the microphone. The user can put acoustic fabric against a table or to the wall. And that thing resends oscillation of the layer to the computer that can decode those signals to sound. The acoustic fabric can use in microphones that are looking like fabric boards. That thing opens new visions in the eavesdrop and recording tools.

The same fabric can use to make new microphones that are allowing to hear things that are happening behind the wall. The idea of this kind of microphone is that the acoustic fabric is put against the wall. And then the user of that system can connect the fabric to the small computer and then to the mobile telephone. That allows sending the information about discussions to long-distance through the internet.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful. Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down. The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
