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. ... >>

Gadget for invigorating the brain during the day 28.06.2021

Specialists from the US Air Force Research Laboratory have developed a device that helps relieve fatigue and maintain performance throughout the day. The VNS technique is based on stimulation of the cervical vagus nerve with electric current.

This method is much more effective than transcranial direct current stimulation (tDCS). Both methods target the locus coeruleus, an area in the brainstem that is the main source of norepinephrine, the wake-up hormone. In this case, tDCS signals must pass through the skin, skull, and the rest of the brain in order to reach the final region.

The duration of the procedure is about 30 minutes. In the case of VNS therapy, exposure is carried out using a portable device. At the same time, a person can independently control the device, and the procedure takes only six minutes.

40 people took part in the tests of the device. Participants were awake for 34 hours. The condition of the volunteers was assessed using four tests. It turned out that participants in VNS therapy showed the best results 12 and 15 hours after stimulation. And while the results need to be confirmed by more research, experts are confident that this method can be a good way to stay alert and productive for a long time.
