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. ... >>

Radically modular electric bike Fabriga Modula 07.05.2023

Cargo e-bikes are a great alternative to cars, but the needs of an e-bike rider can certainly change afterwards. This is where the Fabriga Modula e-bike comes in and can be adapted to the changing needs of users.

The Modula, recently unveiled at the Cargo Bike Summit in London, is made by Italian electric bike manufacturer Fabriga. The Modula frame consists of three sections, fastened with screws: the steering part (front wheel and handlebar); motor part with engine and rear part.

The front section for all bike configurations remains unchanged, but the propulsion inside can be equipped with Brose motors of different power, depending on the weight of the cargo being transported. You can do without an engine if the owner likes to pedal the old way.

The most different section is the back. In particular, a wide and flat cargo platform can be installed on it; place a long luggage compartment and a seat or rack above the rear wheel; fix two high seats with a footrest or one low (for a small child) and one high; one low seat surrounded by a luggage compartment.

It uses a mechanical disc brake, cables are routed inside the frame, there is front suspension plus built-in front and rear lights.

The official release of the Fabriga Modula is scheduled for September, with prices starting at 2770 euros.
