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. ... >>

New Single Lens Technology 10.02.2021

Metalenz intends to fundamentally improve smartphone cameras by replacing modern lens groups in lenses with a single flat lens consisting of nanostructures. A camera with such a lens focuses the image in the same way, but at the same time collects more light for better photos. In addition, the technology allows you to make camera modules much more compact.

Today, every smartphone camera has multiple lenses (lens elements) stacked after each other. In the iPhone 12 Pro, for example, the main rear camera module uses a seven-lens lens. Due to the lens system, manufacturers achieve a compact design and at the same time a sharp, focused image on the matrix.

More lenses allow manufacturers to compensate for issues such as chromatic aberrations (color flaking at the edges of an image) or lens distortion (when straight lines in a photo look curved). However, stacking lenses on top of each other requires more space inside the camera module. This is one of the many reasons why the camera bump on smartphones has gotten bigger and bigger over the years.

Instead of plastic or glass lens elements stacked on top of each other above the image sensor, the Metalenz design uses a single lens built on a glass plate with dimensions from 1x1 to 3x3 mm. The plate is made up of nanostructures one-thousandth the width of a human hair that bend light rays in a way that eliminates many of the shortcomings of classic single-lens systems.

Light passes through nanostructures, which at the microscopic level look like millions of circles of different diameters. Mr. Devlin noted that to control the light flux, achieving the desired result and refracting the rays in a given way, you can simply change the size of such circles.

The resulting image will be as sharp as a multi-lens system: nanostructures will take the job of reducing or eliminating many of the image quality-degrading aberrations found in traditional cameras. Not only does the design save space, which would be a breakthrough, but the developers claim that the new approach allows more light to be captured and directed to the image sensor, resulting in brighter, clearer images even in low light.
