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. ... >>
Random news from the Archive CDT advances P-OLED technology
27.07.2005
With a continued focus on the emerging polymer light-emitting diode (P-OLED) technology, Cambridge Display Technology (CDT) has achieved remarkable results.
An intensive two-year research program led to the appearance of displays with the so-called "upper radiation". The purpose of the program is to prepare the production process for the manufacture of a transparent cathode P-OLED device. Due to this, the service life and efficiency will be increased compared to devices with "lower radiation". An additional result of the program is the "know-how" associated with the manufacture of a transparent cathode.
The development of CDT is already planned to be used by large manufacturers of information display devices. It is expected that improvements in P-OLED technology will speed up the release of finished products based on new panels, including TVs and computer monitors.
