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. ... >>

DVD or FMD ROM 08.01.2003

Will FMD ROM outperform DVD in terms of parameters?

The first parameter is the size/capacity ratio. Here "fluorescent multilayer disk" is beyond competition. The developers claim that even now the first prototypes can accommodate up to 12 GB with a disk size of 5 cm in diameter, that is, on a standard 140-inch drive. This is ten layers. And in the nearest plans of the C3D company there is a desire to at least tenfold the number of layers.

At the same time, the possibility of creating removable storage media with a capacity of tens of terabytes becomes quite real. The capacity that today can only be obtained using huge disk arrays, sometimes occupying entire cabinets and even rooms, will be provided by a compact disk that easily fits in your pocket!

As for the access speed, there is still very little data. The developers promise that this parameter will be much higher than that of DVD. Otherwise, with existing speeds, when working with terabyte arrays of information, even simple operations, such as rereading a disk, can take several hours. New gigantic volumes also require appropriate access speeds.

As for the ratio of capacity / cost of the media, then here FMD ROM has no equal. After all, it is practically a piece of plastic, or rather, a polymer matrix with a photochromic substance, but at a cost, it is just a plastic disk. And no expense to create expensive translucent layers, as in DVD.
