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. ... >>

US military learn to rescue wounded soldiers 18.01.2012

The US Army has adopted a complex and very realistic SimMan medical simulator. It consists of a high-tech manikin and software that simulates various injuries and illnesses.

Blood loss is the leading cause of death on the battlefield today. Therefore, the military needs realistic simulators to help practice quick and decisive actions to save a wounded person.

SimMan is a mobile system that can simulate a variety of situations, from a car accident with a traumatic brain injury and internal bleeding to an explosive injury with amputation of limbs. The mannequin realistically simulates breathing, voice, heartbeat, lung movement, heart rate and other parameters that can be controlled via software.

The SimMan system allows real-time modeling of various complications and monitoring the consequences of a particular medical intervention, which gives doctors the opportunity to gain valuable experience that doctors usually have to gain in critical situations with real patients whose lives are at risk.

To use the dummy in the field, a special version of SimMan 3G based on a laptop computer has been developed. With its help, you can play out various scenarios of emergency assistance and evacuation in an environment as close to reality as possible, for example, by the road, inside an armored car, mountainous terrain, etc. A realistic mannequin, frightening with gaping lacerated "wounds", impresses the soldiers and prepares them for a possible shock at the sight of a comrade wounded in battle.

SimMan is used not only by the military, but also by civilian doctors: for training and advanced training. Upgradable custom software allows you to simulate complex cases that require non-standard actions. There are also variants of mannequins for training surgeons and pediatricians.
