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 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.

Random news from the Archive New helmets of the Swiss Guards are printed on 3D printers 24.03.2019 The Vatican's Swiss Guard, a colorfully dressed mini-army meant to protect the Pope, has received new 3D-printed helmets. The plastic helmets were handed over to the corps on the 513th anniversary of the founding of this branch of the armed forces - the oldest surviving to this day. Externally, the new helmets are almost identical to the previous version, but they show the coat of arms of Pope Julius II, who settled on Swiss soldiers when creating a unit for his personal protection. One of the main advantages of the new helmets is that they will not get as hot in the sun as the old ones made of metal. In addition, metal helmets made in Austria weighed 2 kg each, while new ones made in Switzerland weigh 570 g. The helmet is part of the ceremonial uniform, with its recognizable variegated combination of red, yellow and blue stripes, worn during official papal services and visits by heads of state. At other times, the guards, who number about 110, wear a simpler blue uniform with a beret.
