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. ... >>

MDM diodes 19.09.2013

Thanks to research at the Oregon State University College of Engineering, MDM (metal-dielectric-metal) diodes are one step closer to being used in real devices. Three years ago, the university announced the first successful high-speed MDM diode and continues to be a world leader in this technology.

MDM-type diodes (MIM - metal-insulator-metal) are a "sandwich" of two metals with two dielectrics between them. This allows electrons to tunnel through the dielectrics and emerge almost instantly from the other side. Now researchers have found that adding a second dielectric allows for "stepping tunneling" - a situation in which an electron can only tunnel through one dielectric, rather than two. This, in turn, allows precise control of asymmetry, diode non-linearity, and rectification at low voltages.

"This approach allows us to improve device performance by creating additional tunneling barrier asymmetry," said University professor John Conley. "This gives us another way to organize quantum mechanical tunneling and brings us closer to the real devices that will become possible with this technology." .

MDM devices consist of four layers (from left to right): amorphous zirconium, hafnium oxide, alumina, and aluminium. The image was obtained using a transmission electron microscope.

“Thanks to MDM diodes, more complex microelectronic devices become possible,” the scientists say, “not only improved liquid crystal displays, mobile phones and televisions, but also devices such as extremely fast computers that do not depend on transistors, or infrared radiation “energy storage” - as a way to produce energy from the cooling of the Earth during the night."

"MDM diodes are faster devices than silicon chips and can be produced on a huge scale at low cost from inexpensive and environmentally friendly materials," the university says.
