Countries around the world have put innovation first in development and strived to seize the commanding heights of science and technology. Recently, scientific research institutions and colleges of various countries have devoted themselves to research in professional fields, continuously improved their scientific and technological strength, achieved fruitful technological innovation results, and innovatively developed batches of high-precision instruments and equipment. Let’s take a look:
Switzerland invented a new type of power-free signal receiver
Researchers at the Swiss Federal Institute of Technology in Zurich used the principle of energy capture technology to propose a new power-free signal receiving technology solution and have successfully developed a prototype. It is reported that this power-free signal receiving technology has a wide range of application prospects, such as contact sensors for controlling car door locks and starting engines, and its reliability and safety will be much higher than the current radio frequency identification technology. It is also such as communication between wearable electronic devices, and the realization of “handshake information exchange” between different users.
With the help of immunochromatography, Russia has developed a high-precision blood quantitative test method
Recently, Russian researchers have developed a blood quantitative test system. The system uses immunochromatography and magnetic nanoparticles as detection targets. It can accurately detect the concentration of protein molecules in opaque or even dark-colored liquids, and can achieve high-precision quantitative testing. The system can achieve rapid testing within 30 minutes, does not require special training for operators, can be used in field conditions, and can be extended to food and drug testing. The relevant results were published in the academic journal “Biosensors and Bioelectronics”.
Chinese scientists have made important breakthroughs in the field of ultra-strong carbon nanotube fibers
With the support of the key project of “Nanotechnology” in the National Key R&D Program, a team of professors from Tsinghua University has made breakthroughs in the field of ultra-strong carbon nanotube fibers, and reported the preparation of ultra-long carbon nanotube bundles with theoretical strength close to that of a single carbon nanotube for the first time in the world. This work reveals the bright prospects of ultra-long carbon nanotubes for the manufacture of ultra-strong fibers, and at the same time points out the direction and method for the development of new ultra-strong fibers. The relevant results were published online in Nature Nanotechnology on May 14, 2018.
South Korea has developed an ultra-precise artificial skin sensor without power supply
South Korea has developed an ultra-precise skin sensor that can be activated without power supply. The skin sensor has very precise sensing capabilities for measuring blood pressure, electrocardiogram, surface characteristics of objects, etc. The researchers said that this research is different from the previous silicone-based sensors. It is a new type of sensor, which is of great significance for measuring biological signals, developing and improving the performance of robot skin. In the future, it is possible to further build a power-free, high-sensitivity sensor detection system connected to the physical network, which can be widely used in various industries.
“You can’t sit and talk about things, and you can’t talk about things in vain.” Science and technology and innovation are the main driving force for economic and social development and the main channel for improving productivity. Under the new economic situation, the country has placed scientific and technological innovation in an important position in development, vigorously implemented the development and innovation strategic planning, and created a large number of “national heavy weapons” that have amazed the world. Standing at a new starting point, countries around the world are accelerating their innovation layout and sounding the new horn of building a world science and technology power.
