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. ... >>

Puncture-free blood sugar patch 21.04.2018

Every day, millions of people with diabetes are forced to prick their skin to measure their blood glucose levels. In the future, this unpleasant procedure will be done away with: smart contact lenses and a graphene-based patch are a direct confirmation of this.

Developed by scientists from the University of Bath (UK), the patch is applied to the skin without damaging its surface. It is equipped with miniature sensors that use a weak electrical current to remove glucose from the interstitial fluid that surrounds our cells. The extracted glucose is collected in tiny tanks where its concentration is measured. This allows you to get accurate readings of blood sugar levels with a given frequency: from once every 10-15 minutes to several hours.

A low-cost disposable device can transmit these readings to an app on the user's smartphone, alerting them to abnormalities.

In laboratory tests, the patch has been successfully tested in healthy volunteers and in pigs with elevated glucose levels. The next steps are to optimize the number of sensors, increase the operating time of the device to 24 hours, and conduct clinical trials on patients with diabetes.
