Artificial leather for touch emulation
15.04.2024
In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>
Petgugu Global cat litter
15.04.2024
Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>
The attractiveness of caring men
14.04.2024
The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
| Random news from the Archive Highly sensitive camera will search for extraterrestrial life and dark matter
21.11.2019
Researchers from the US National Institute of Standards and Technology (NIST) have created the most highly sensitive camera to date, the pixels of which are sensors that can capture single photons of light. This camera has more than a thousand pixels on its sensor and is designed to be installed on next-generation space telescopes, where it will be used to search for chemical signs of life on other planets, searches for the elusive dark matter, which accounts for most of the entire matter of the Universe.
Each pixel of the nova is a tungsten-silicon nanowire, 3.5 millimeters long, 180 nanometers wide, and 3 nanometers thick. These nanowires are placed on a silicon substrate and connected to the "outside world" by wire connections made of superconducting niobium. This pixel arrangement of the camera provides the best speed, efficiency and color range available today. Such sensors have already been used by NIST specialists in the past to study the phenomenon of quantum entanglement, which Albert Einstein called "ghost action at a distance."
In addition, a new type of photosensitive sensors has a very low level of intrinsic noise, which eliminates the possibility of false positives and data distortion. This feature is extremely important for dark matter searches and space astronomy, where it is necessary to capture single photons with the lowest energy, photons located at the farthest end of the infrared range.
The NIST camera is small in size, its crystal is a square with a side of 1,6 millimeters, on which 1024 sensors are placed in the form of a matrix of 32 by 32 pixels. With such a dense arrangement of pixels, NIST researchers first encountered the problem of overheating of the camera crystal, but later, by expanding the electrical conductors of the information reading circuits, this problem was successfully solved.
Now researchers have already achieved that 99,5% of fully functional sensors are obtained at the output of the production technological line. The next steps that scientists intend to take will be to increase the efficiency of pixel sensors in order to increase their sensitivity in the boundary ranges. And only after that, the researchers plan to start creating large versions of cameras, the number of pixels in which will be in the millions.
The parameters of the new camera were measured at the NASA Jet Propulsion Laboratory (JPL) and at the California Institute of Technology. After all, only there is all the electronics necessary for such measurements, which is now used to develop and implement optical communication systems in deep space.
