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. ... >>

Electric tractors 23.07.2022

Indian startup Cellestial E-Mobility, a subsidiary of Tube Investments of India (TII) and Murugappa Group ventures, has officially unveiled India's first electric tractors.

The startup developed three models of tractors with power from 27 hp at once. up to 55 hp The sale of electric tractors is planned within the next three months.

Tractors will cost comparatively less than units with a conventional standard diesel engine. The price is expected to be between $7570-$10090.

"Electric tractors are designed for use in the field, as well as in gardening or greenhouses. The machines are equipped with an Indian household socket for recharging. Electric tractors can cover a distance of up to 75 km on a single charge and reach speeds of up to 25 km / h. At the same time, the units have a PTO, hydraulics and all-wheel drive," the manufacturer said in a statement.

Charging the battery of the electric tractor is carried out using a basic household charger from a conventional single-phase 16A socket, this process takes about 6 hours.

At the same time, thanks to the industrial charging station, the battery can be charged even faster, for example, in just 2 hours. The tractors are also equipped with regenerative braking and power inverting functionality, allowing them to power their own UPS for backup power.
