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 ... >>

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. ... >>

Artificial intelligence controls the tanker 15.06.2022

Hyundai's HD division, Hyundai Heavy Industries, organized the world's first transoceanic voyage of a large autonomous gas tanker.

This technology made it possible to do without human intervention in control during a journey of several thousand kilometers, according to Korea Times.

During the experiment, the ship traveled 10 kilometers autonomously during a voyage from Freeport on the southern coast of the Gulf of Mexico to South Korea's Boryeong terminal. The flight was operated by SK Shipping, a division of the diversified concern SK Group.

According to the developers, in the future it is planned to introduce autonomous systems not only on commercial cargo ships, but also on small-tonnage entertainment yachts. So far, in the testing mode, the vessel had a crew on board, but people did not interfere with the operation of automation at all throughout the entire 10 km of autonomous navigation.
