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. ... >>

Images are projected onto clean air 07.05.2004

A small American firm "102 Technology" has developed a method for projecting images into clean air.

The projector can work as a TV or computer monitor. Screenless projectors are known to throw an image onto a curtain of laminar fog or steam, but here a high-quality color image appears simply in the air above the projector.

So far, only two prototypes of the projector have been made: one gives an image with a diagonal of 105, the other - 38 centimeters. The image can be interactive, that is, you can use your hand, like a computer mouse cursor, to drag file icons and turn on one or another computer function.

Since the patenting of the device and process has not yet been completed, the company representatives do not give out a secret. They only say that a laser is used and that for work the projector passes air through itself without adding anything to it.
