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. ... >>

Echo sounder for drone 08.03.2020

Bats are able to fly through total darkness using echolocation. So why not use the same principle in unmanned vehicles? Scientists at Purdue University have taken this question to heart and developed a system that allows a drone to navigate in space using just four microphones and a speaker.

The principle of the system is incredibly simple. The speaker emits a sound, this sound is reflected from the surrounding objects and is picked up by the microphones. The speed of sound is constant. This means that by the time during which the microphone picks up the reflected sound wave, it is possible, using simple mathematical calculations, to determine the distance to the object from which the sound was reflected. With four microphones at your disposal, you can create a detailed XNUMXD map of the environment around the drone. And all this - without a single camera. Moreover, the technology is able to work not only in the air. It can be effectively used on land or water equipment.

Of course, the development is not yet perfect. Currently, the drone is supposed to hover in place during sound scanning, but in the future, the developers plan to upgrade the system by teaching the drone's on-board computer to perform calculations in motion.

According to scientists, in some cases, echolocation works more reliably than visual pattern recognition. Sometimes the camera can be wrong. An unmanned drone "sees" a non-existent wall in front of it and hangs in indecision. Echolocation has no such problems. When used in conjunction with existing computer vision systems, unmanned vehicles can achieve amazing accuracy.
