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 deformation is precisely reproduced in the second tissue that comes into contact with the baby's skin, allowing him to feel physical closeness, even at a distance.

Electrodes on both sides of the film react to deformation by changing its electrical capacitance. Intelligent algorithms predict and programmatically control the sequence of movements, controlling the deformation of the elastomeric film and emulating the parent's touch.

Artificial skin technology for virtual hugs opens new horizons in the field of virtual communication and intimacy. This development could be a valuable tool for those who are away from their loved ones, especially children quarantined in hospitals. Emulating touch from parents can bring solace and comfort to children during difficult times, as well as strengthen the bond between parents and children over a distance.

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

High Energy Density Capacitor 17.05.2024

Energy plays a key role in many aspects of modern life, and the ever-increasing demand for efficient and fast-charging power sources is driving innovation. Researchers at the McKelvey School of Engineering at Washington University in St. Louis have taken a significant step forward with a high-energy-density capacitor that promises to revolutionize the world of energy. A team of scientists from the McKelvey School of Engineering at Washington University in St. Louis presented the results of their latest research on heterogeneous thin-film structures for capacitors. Researchers, working with ferroelectrics, inadvertently created a capacitor with an amazing energy density that is 19 times higher than that of conventional elements. This breakthrough opens up new prospects for the development of fast-charging batteries, which are so necessary in the modern world. Capacitors play a key role in various devices, providing stable ... >>

Causes of conflicts between brothers and sisters 16.05.2024

Family relationships are often complex and multi-layered, and conflicts between siblings are no exception. Research in this area can help us understand what factors underlie these conflicts and why they occur so frequently. Let's look at some of the findings from psychologists at Arizona State University. American psychologists from Arizona State University conducted a study aimed at identifying the causes of conflicts between brothers and sisters. They found that different forms of violence, whether physical or verbal, did not depend on the gender of the siblings. This means that both girls and boys can exhibit aggressive behavior towards their loved ones. Other studies have shown that conflict between siblings often persists into adulthood, even as contact decreases. This indicates that people often follow established patterns of behavior formed in childhood. It was also found that, despite ... >>

Treatment of herpes with infrared light 04.07.2004

"Fever" on the lips - a manifestation of the herpes virus, which infects about 95% of the population - is usually treated with either home remedies or special antiviral creams.

The English firm Virulight has begun production of a pocket device for the treatment of herpes. The razor-sized device, powered by a built-in battery, irradiates damaged skin with infrared light at a wavelength of 1072 nanometers. Usually, two irradiation sessions of three minutes are enough to eliminate the virus, in more complex cases - up to seven sessions.

If you capture the disease at the initial stage, when it manifests itself only in tingling in the corners of the lips, one session is enough. The entire treatment takes half the time of an antiviral cream treatment. The light actually does not affect the virus, but the immune cells of the skin, stimulating their activity, and they drive the virus into a dormant state when it does not manifest itself.
