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. ... >>
| Random news from the Archive A new class of metamaterials capable of changing their physical properties
18.12.2018
Modern metamaterials are very similar to the technologies we know from science fiction. Due to the unique properties of such materials, it is possible to create incredible things, invisibility cloaks that hide objects in various wavelengths of the electromagnetic spectrum, and in practice, such technologies are already used in mobile phone antennas, for example. Note that all metamaterials, which we have talked about more than once on the pages of our site, have a set of fixed properties, albeit unique, which significantly limits their scope.
Researchers at the Lawrence Livermore National Laboratory (LLNL) and the University of California San Diego have developed a new class of metamaterials, mechanical metamaterials that can become rigid or flexible in response to an external magnetic field.
To create a new miracle metamaterial, the researchers used the so-called 4D printing technology. This technology got its name from the fact that objects made using three-dimensional printing can change their shape over time, which acts as the fourth dimension. As a rule, changes in the shape of an object occur under the influence of some external factor - high temperature, hydration, exposure to a magnetic or electric field.
The new technology is based on materials capable of responding to external fields (FRMM, field-responsive metamaterial). However, unlike the materials used in other 4D printing technologies, FRMM materials do not change their shape, the changes affect some of their physical properties, hardness, in this case. The creation of FRMM materials turned out to be quite simple - instead of a monolithic structure of the printed object, a tubular hollow structure is formed. And these cavities at the next stage are filled with a special magnetic fluid.
A ferrofluid consists of tiny particles of a magnetic material uniformly dispersed in a volume of a non-magnetic solvent. When such a liquid is exposed to an external magnetic field, the particles in its volume become ordered, aligning themselves along the lines of the magnetic field, and the material turns into a practically solid monolith. In the absence of a magnetic field, the ferrofluid behaves like an ordinary viscous fluid, capable of flowing freely in any direction.
