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. ... >>

Free Micro Bit Computers to Learn Programming 26.03.2016

The British Broadcasting Corporation BBC has begun deliveries of a Micro Bit single-board mini-computer designed to teach programming to schoolchildren.

The Micro Bit platform was introduced exactly a year ago - in March 2015. The hardware component includes an energy-efficient ARM Cortex-M microchip, an accelerometer and magnetometer, a Bluetooth LE wireless adapter, and a matrix of 25 (5 x 5) LEDs. There is a Micro-USB interface and two programmable buttons.

The dimensions of a single board computer are only 50 x 40 mm. It can be powered by a AAA battery. As programming environments for Micro Bit, its creators offer Blockly, Python and TouchDevelop.

Starting March 22, Micro Bit is being delivered to UK schoolchildren aged 11-12 and teachers whose schools are registered with the BBC programme. In total, the broadcasting corporation intends to supply one million single-board computers free of charge.

In the future, Micro Bit will go on sale, so that everyone can purchase the product. The price has not yet been specified, but it is unlikely to exceed $10.
