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 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.

Random news from the Archive Satellite communications in the 300 GHz band 08.02.2017 Panasonic, together with colleagues from the University of Hiroshima and the National Institute of Information and Communications Technology, have achieved some success in developing a transmitter capable of transmitting data at over 100 Gbps over a single channel in the 300 GHz band. The emergence of this technology, at least an order of magnitude faster than the 5G network, is expected around 2020. Last year, this group of researchers showed the use of QAM modulation in the radio channel in the 300 GHz band. This year, the speed per channel was increased six times - up to 105 Gbps. Scientists intend to continue development. The allocation of the currently unused 275-450 GHz frequency band, which includes the 290-315 GHz band in which the transmitter operates, will be discussed at the World Radiocommunication Conference (WRC) in 2019.
