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. ... >>

Assessment of emotional stress in the cinema 29.10.2018

Researchers at the Chemical Institute of the Max Planck Society have come up with a chemically objective way to give films an age rating. They measured the composition of the air during 135 screenings of eleven different films; the total number of spectators was over 13 thousand people. A special chemical analysis device was installed in the ventilation system of the cinema hall to take air samples every 30 seconds. The authors of the work paid special attention to volatile organic substances, comparing their level with the genre of the film and the age of the audience.

It turned out that the emotional stress experienced by the audience while watching the film corresponds to the level of isoprene. It is best known as a natural rubber monomer and one of the products of petroleum refining. However, isoprene is also formed in our bodies during metabolism, accumulating in the muscles and escaping through the skin and lungs when our muscles work. If we watch something that makes us nervous, we start to change position, fidget, grab onto the armrests, etc. - and because of such muscular effort, isoprene flies into the atmosphere of the cinema hall.

Accordingly, the emotional impact on children and adolescents is quite easy to assess by the level of isoprene. This method can be used in controversial cases, when it is not very clear how exactly the children will react to the film.

The researchers emphasize that we are talking about psychological stress. They would also like to find out what other emotional states can be caught in a similar chemical way - after all, the air was analyzed for sixty compounds, and it is quite possible that among them there are some chemical signs of calm sadness or, say, fun. But here it is already necessary not only to catch the air in the cinema hall, but to arrange a carefully controlled laboratory experiment.
