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. ... >>

Electricity from clothes 31.10.2020

Scientists in Switzerland have found a way to generate electricity using wear-resistant polymers applied to clothing.

Until now, solar concentrators have only existed in the form factor of rigid, airtight cells. This made them unsuitable for use in the structure of textile materials. But now everything has changed. The discovery made by Swiss scientists is based on materials that are able to use even scattered light to generate energy.

These materials contain luminescent solar concentrators (LSCs) that capture ambient light and transfer its energy to a solar cell, which then in turn converts the light into electrical energy. The discovery was made by a research team led by Luciano Boesel from the Biomimetic Membrane and Textile Laboratory of the Swiss Federal Laboratory for Materials Science and Technology (EMPA).

It was they who found a way to incorporate these luminescent materials into a polymer fabric that is flexible and breathable. This new material is based on the properties of linear and hyperbranched amphiphilic block copolymers, which are already on the market in the form of silicon hydrogel contact lenses.

With the help of colleagues specializing in photo-energy and fibers, Luciano Bozel's team was able to turn it into a flexible solar concentrator. Amphiphilicity (otherwise diphilicity) is a property of molecules of substances, usually organic, that have both hydrophilic and hydrophobic properties, that is, under certain conditions they pass water, and under certain conditions they repel.

The new solar concentrator can be used to create textile fibers without the textile becoming brittle and susceptible to cracking or water vapor accumulating in the form of sweat. Body-worn solar power concentrators offer us huge promises and benefits in the ever-increasing demand for mobile energy sources for portable gadgets and devices.
