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 ... >>

Random news from the Archive Icis smart glasses from Laforge Optical 20.02.2014 "Glasses are first and foremost a fashion accessory," Laforge Optical decided. And if the developers from Laforge are seriously determined to create a technological device that stands out from the competition, waving to push the Google Glass gadget off the pedestal, then they should do this by hitting the most vulnerable part of the creation from Google - its design. Icis smart glasses, available now for pre-order, will not only embody the technological advancement of their owner, but also show that the owner of the device also has good taste and understands modern fashion. As for the technical characteristics, Icis will have the classic functionality for this class of devices: a camera (it will be absent in the beta versions of the gadget), a microphone, a speaker and a touchpad, and the glasses will act as displays, while covering the maximum field of view available for glasses. A friendly interface will automatically convert notifications from smartphones and other mobile gadgets running iOS, Android or Windows operating systems into an informative visual image on the lenses. The image resolution of the final Icis model with the Bold index will be 800x600 pixels, but the prototypes available from the middle of this year will have more modest parameters. "Our main competitor is Google Glass, but the approach chosen by Laforge Optical specialists in creating Icis differs radically from the concept of competing companies. We are focused on creating a gadget that strangers would not pay close attention to," the CEO and Corey Mack, founder of Laforge Optical. "Smart glasses" Icis are a symbiosis of modern fashion trends in accessories and the main technological solutions used in devices like Google Glass. True, in this case, the owner of such a gadget will not need to constantly look away at the display, which is not very conveniently located in the upper right corner - the entire surface of the Icis lenses will become an interactive display. One of the innovative tasks set before the developers of Laforge Optical is to solve the problems of software compatibility of Icis with various platforms. For this, the SocialFlo application was created, which is responsible for sending notifications from installed applications on your mobile device and operator network. You just need to download the software to your smartphone and sync it with the Icis smart glasses via Bluetooth. The creators of the device noted that their gadget will have three main modes of operation: normal, active (with a limit on the number of notifications displayed) and the "Drive" mode, which will filter all transmitted information that is not related to the process of driving a car. Icis will also go on sale in three different versions, giving the buyer the right to choose exactly the style that he most sympathizes with. As for the cost of new items, here the price is differentiated depending on the type of kit and version of the device. By leaving a deposit of $ 220 to participate in the testing program, you can get acquainted with the early prototype of the gadget. If you want to become the owner of the basic Icis Early Beta Kit (IEBK) immediately and without any obligations, you will need to pay $820 for the device. In this case, you will be able to start full-fledged testing in the summer of this year. At the end of 2014, the next modification will appear - Icis Early Kit (IBK) at a price of $420, and you can upgrade the previous version of "smart glasses" to the IEK version by sending your gadget back to the manufacturer. It will also be possible to exchange the Icis Early Kit for the already serial version of Icis, paying an additional $200 for this. The final release, which implies the launch of the Icis Bold model, is scheduled for early 2015. Here, buyers can already choose from three stylistic solutions for the gadget. The technical characteristics of the novelty will also change: the resolution of the lenses will be equal to 800x600 pixels, while in IEBK and IBK it was, according to preliminary information, 640x480 pixels.
