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. ... >>

Car tires with living moss inside 19.03.2018

Goodyear presented at the next Geneva Motor Show a very unusual concept - Oxygene tires with living moss inside, which absorbs carbon dioxide and produces oxygen.

It is assumed that such tires will be able to generate energy through photosynthesis. As planned by the company, they will absorb CO2 from the air and moisture from the road surface, nourishing the moss inside the sidewall, and produce oxygen. Goodyear estimates that in a city the size of Paris with about 2,5 million cars on the road, the widespread use of Oxygene tires will generate about 3 tons of oxygen and absorb more than 000 tons of carbon dioxide per year.

In addition, the concept tires use the resulting energy to power the internal electronics, in particular the built-in sensors and the data processing unit. It is also noted that the tires will use Li-Fi technology, which will allow them to "communicate" with other cars and road infrastructure. The treads, according to Goodyear, will be 3D printed from rubber powder obtained from recycled tyres.
