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. ... >>

200MP ISOCELL HP1 image sensor 09.09.2021

The South Korean company Samsung announced the ISOCELL HP1 sensor. It became the world's first smartphone image sensor with a resolution of 200 megapixels (16 x 384 dots).

Samsung ISOCELL HP1 has not the largest pixels. Their size is 0,64 microns. According to the manufacturer, the compact dimensions of the matrix allow solving the problem of integration into thin smartphones, where every millimeter of free space is worth its weight in gold.

The sensor supports ChameleonCell technology, which is responsible for improving the quality of materials in the absence of light. When combining 16 pixels, the size increases to 2,56 microns, and the smartphone can take pictures in twilight and darkness with a resolution of 12,5 megapixels.

Samsung ISOCELL HP1 supports 8K ULTRA HD video recording at 30 FPS. Recording is carried out in 50 megapixel mode by combining four neighboring pixels.
