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. ... >>

inflatable tablets 01.02.2019

Scientists have developed a jelly-like pill that inflates to the size of a ping-pong ball when it enters the stomach. Such tablets can be used to monitor tumors or ulcers. The device was inspired by the puffer fish, or puffer fish, which can quickly inflate when it feels threatened.

The MIT team behind the invention claims the pill can last up to a month in the body. The innovation has already been tested on pigs.

The tablet was made from two types of hydrogel: the inner layer consists of absorbent particles, and the outer one with a protective membrane. This gives the invention a jelly-like consistency, helps it rapidly increase in size in the stomach and thus prevents it from leaving the body.

The inflatable tablet can be removed from the body at any time by drinking a calcium solution. This will help her quickly shrink back to her original size. The new tablet is softer and lasts longer than alternatives, which are often made of hard plastic or metal.
