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. ... >>

2D transistor analog op amp 18.09.2020

A team of researchers from the Vienna University of Technology (Austria), the University of Pisa (Italy) and AMO (Germany), who successfully demonstrated a 2D microprocessor a few years ago, recently fabricated an analog operational amplifier using an atomically thin (2D) semiconductor, molybdenum disulfide (MoS2 ).

Thanks to the homogenous MoS2 film grown by chemical vapor deposition, it was possible to obtain transistors with excellent performance: low hysteresis, ON/OFF ratio exceeding 8 orders of magnitude, mobility up to 20 cm2/Vs. A test of more than 40 devices showed good reproducibility of these indicators with small variations in threshold voltage and charge carrier mobility.

These results allowed the authors to design a 4-stage device with a total gain of 40 decibels. It is based on n-channel field-effect transistors with a local rear gate and is one of the most complex analog circuits developed to date on monolayer semiconductors.

To demonstrate the potential of their op-amp, the researchers used it to fabricate a number of typical feedback circuits, including an inverting amplifier, an integrator, a logarithmic amplifier, and a transimpedance amplifier.

Although the op amp is still at the prototype stage and will continue to improve, the analysis carried out indicates the possibility of its production on an industrial scale.
