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. ... >>

5th generation BMW electric motor without rare earth magnets 24.01.2022

The new and most powerful electric crossover BMW iX M60, first presented at CES 2022, will receive two branded fifth-generation electric motors, with a total output of 455 kW / 619 hp. and a maximum torque of 1100 Nm. The car accelerates from 0 to 100 in 3,8 seconds and can travel up to 575 kilometers without recharging. The maximum speed is 250 km/h.

To achieve such impressive performance, BMW has developed an electric magnetless motor that combines old-school sensibility with modern electric motor technology. And it does not use rare earth metals.

The BMW Gen5 eDrive operates as a three-phase AC synchronous motor, while at the same time containing brushes and a commutator to power the rotor windings. The company hopes that modern materials and new sealing technologies will ensure a longer life for the new engine. In the collector motor, the "minus" was that the brushes and collectors wore out and dust formed, as a result of which they need to be changed periodically. But the brush modules of the new BMW electric motor are placed in a sealed compartment, which prevents dust from entering the stator/rotor wiring.

According to the automaker, the fifth generation engine has greater energy density, better heat dissipation and higher switching frequency. All this gives higher revolutions, greater torque and power.

The fifth generation of BMW eDrive technology also includes a drive unit in which the electric motor, system electronics and transmission are integrated into a central housing.

Luxury brand Bentley introduced an electric motor design back in 2020 that does not use rare earth magnets. And in 2021, the German company Mahle has developed a car electric motor without permanent magnets.

Rare earth metals are increasingly difficult to mine. China controls over 90% of the world's reserves. Therefore, various companies are looking for ways to do without them.
