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. ... >>

Prosthetic arm rocket engine 28.10.2007

US engineers have adapted a rocket engine for a prosthetic arm.

"We have created an artificial hand that resembles a human hand much more in its work and strength than all existing prostheses. In addition, it weighs about the same as a human hand," says Professor Michael Goldfarb from Vanderbilt University, leader of the work. (USA).

Until now, prosthetic arms have run on batteries - their energy was enough to provide a limited set of functions. However, for a complex hand that could, for example, move its fingers, the battery turned out to be weak.

Therefore, scientists from Goldfarb's group decided to adapt a rocket engine for the prosthesis. This was done by specialists from Johns Hopkins University - the engine became the size of a pencil. And it works on hydrogen peroxide, which decomposes with a catalyst. The result is pressure that opens and closes a series of valves, and the hand and fingers move. A small vessel of fuel, which is placed in the forearm, is enough to power an artificial arm for 18 hours.

When creating the hand, two problems arose. The first is warmth. They coped with it by covering the hottest parts with special plastic. The second is the exhaust: when the peroxide decomposes, water is obtained, which must be put somewhere.

The authors of the work applied an ingenious solution: water passes through a porous surface, and its amount approximately corresponds to the volume of sweat emitted by a human hand.
