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 Verbatim LED lamps with glare-free light output 27.06.2015 Verbatim's 10,5W retrofit lamps avoid the flickering effect often found in LED lamps from other manufacturers, thanks to a unique design: the lamp imitates the light output of a halogen lamp, directing the light beam into a reflector. The new AR111 lamps use an advanced thermal management system with a compact heatsink that weighs only 100g, and the narrow mounts allow them to be installed in a variety of luminaire types, which is almost impossible with lamps from other manufacturers without sacrificing energy efficiency and performance. In addition, the reflector has an unusual mirror finish, which makes the lighting even brighter and also gives the luminaire a more elegant look. The new Verbatim lamps are suitable for general and spot lighting in public areas: reception areas, corridors, stairwells and shops where the lights are always on. The line includes models with different color temperatures: 2700, 3000 and 4000K, emitting a luminous flux of 680 lm, 700 lm and 740 lm, respectively. The luminous efficiency of the lamps of this series is 71 lm / W, and the service life is 40 hours. A 000W LED lamp that emits 10,5lm is equivalent to a 750W halogen lamp. "The use of LED lamps can significantly save energy consumption compared to halogen lamps, which is why our AR111 series lamps are very popular with customers. In addition, the lamps provide optimal light distribution without glare and light scattering, as opposed to LED lamps from other manufacturers, - commented Dick Hugerdik, General Manager, Verbatim's LED Lighting EUMEA, "The positive feedback we've received so far on the new products will enable us to increase sales in this segment of our business."
