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. ... >>

Adhesive frameless solar panels 29.05.2021

In the future, solar panels may become a ubiquitous element of the exterior decoration of buildings and structures. But not in its current form, which involves complex installation work on a fairly strong frame. A breakthrough promises to be frameless solar panels proposed by Singapore-based Maxeon Solar Technologies. Maxeon Air panels are lightweight, flexible and adhesive-backed for easy installation on any surface.

For the first time in nearly 50 years of solar panels, the complex work and costly associated costs of deploying solar farms can be eliminated. Today, solar panels are quite heavy and large plates that must be installed on a special frame. Not every roof will withstand a truss of such panels, in which, when designing buildings, adjustments were not made to resist excessive load. With Maxeon Air panels everything will be much easier and these are not all the innovations they have to offer.

The basis of the Maxeon Air panels allows gluing and peeling off the panels during installation. They are flexible and, up to a certain limit, without cracking, can repeat the bend of the roof or other surface on which they will be mounted. The efficiency of the panels is quite high and reaches 20,9%. They can generate electricity even in a shaded state, in which most modern panels would simply turn off.

Maxeon Air panels weigh half as much as conventional panels - 6 kg/m2. It is expected that such panels will be massively installed on the roofs of commercial buildings that have not been built up with sufficient safety margin. In Europe, for example, 4 GW will be collected from such roofs, and testing of the capabilities of Maxeon Air panels will begin from Europe. The company expects that a number of pilot farms will be deployed before the end of this year, and next year the Maxeon Air panels will go on sale.
