Artificial skin can be useful in next-generation touch screens and robot sensing.



Artificial sense of touch can use in burglary alarms. And it can also use in submarine shells. If submarine has sense. It can feel as if somebody try to connect mine to it. If an artificial sense of touch has got enough high accuracy, that thing makes it possible to use it as fingerprint recognition. We could make artificial touch by using layers where are lots of nano-size lasers. Those layers can detect the place where the finger is moving. 

Or the screen-size CCD chip can detect the point where a person moves their hand. In that case, the system measures the distance between the sensors and the object. And it can use an image detector to separate the objects that are touching it from the background. In that case, the optical system acts like the sense of touch.  

Today artificial sense is used in touchpads. Two layers touch each other or touch causes a tunneling effect that makes electricity travel to a certain point. The same technology can use to make artificial sense for submarines, robots, and other stiff layers. There are many ways to make artificial sense. The piezo-electric crystals can use for that purpose. 

If the artificial sense needs to work in extremely low temperatures it can use the same technology as scanning tunneling microscopes. The system senses the distance between two layers by using particles. That hovers between them. Also if something touches those layers it sends energy to those particles. And that thing can use as sense. 

Another way is to use optical fiber. When something pushes the material. That stretches optical fiber. And if there are sensors in the middle of the optic fiber net those sensors can sense the differences in laser light. 

Things like nano-size laser LEDs can also measure the distance between an elastic shell and another shell. When something presses the elastic shell that thing causes the difference between their distance. 

Artificial skin with an artificial sense of touch is one of the most important things if we want to create robots that act like humans. The artificial sense of touch makes robots act like humans. And if somebody touches the robot's shell, the robot feels that thing. That allows the robot to operate in poky places. And in that case, the robot must not use cameras. If robots have different senses. That makes it possible to automatize their actions differently than if the robot uses only active sensors. 

If the sense tells that something touches the robot, it can send information about that thing to the command center. Or it can activate a process that makes the robot take a distance from the wall. Artificial skin can be an extremely good thing for burglary alarms. Or if the submarine is covered by using that thing, it can warn if somebody tries to connect mines or some unauthorized things to the submarine's shells.

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
