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 ... >>

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.

UAVOS drone with record run time 27.01.2020

The Robinson R22 helicopter became the basis for an unmanned aerial vehicle, which UAVOS introduced some time ago. Unlike most rotary wing drones powered by electric motors, this product differs in size and in that it is equipped with a gasoline engine. As a result, the UAVOS drone can lift up to 180 kg (40 kg with a full fuel tank) and fly up to 1020 km.

The unmanned helicopter is designed to deliver goods and provide humanitarian assistance. It can stay in the air for up to 6 hours and fly in much more difficult weather conditions than small electric drones. For takeoff and landing, he needs a platform with dimensions of 15 x 15 m.

The cruising speed is 160 km/h, the working ceiling is 4200 m.
