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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Gesture recognition system based on 60-GHz radio waves 08.06.2015

The saturation of the space surrounding a person with radio frequency radiation today is such that developers are seriously creating solutions for extracting energy from the "air". Infineon and Google will contribute to the development of research on this topic.

The German concern, together with the Google ATAP (Advanced Technology and Projects) division, has developed and will soon demonstrate a solution for recognizing the presence of a person and his gestures using special radars operating in the 60 GHz band.

The first demonstration of a fully working platform will take place as part of the Google I/O Developers Conference in San Francisco. The recognition unit consists of Infineon's RF engineering: 60 GHz transceiver, antenna and control electronics, all in one compact package designed for embedded applications. Such a recognition system is also useful for robotic vision systems, for car security systems and for vending machines. The "radar" module can be built into both wearable electronics and stationary devices.

From the point of view of modern biology, such low-power high-frequency radiation does not have a detrimental effect on human health, but at first, X-ray machines were also considered safe and were used until they were installed in shoe stores to try on shoes. For some it ended badly.

Recall that systems have already been developed for determining a person and objects behind a radio-transparent wall based on compact microwave radars.
