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. ... >>

Insect robots with ion-powered engines 01.02.2019

Nature has many interesting inventions that a person is not ashamed to copy and use in everyday life. Millions of years of evolution have created a miracle of everything that surrounds us. A person is trying to bring some of this experience into the world of robotic technology, for example, considering it valuable for creating flying insect robots. As a consequence, dragonfly robots or bee robots appear. However, the difficulty of scaling the flywheels and, as a result, the decrease in controllability makes it necessary to look for other non-natural sources of lift for miniature aircraft.

Scientists from the University of California at Berkeley have proposed using ion propulsion for insect-scale robots. The principle of operation of such ion engines is that positively charged ions (mainly nitrogen) rush from electrodes under a very high voltage to a lattice with an opposite charge. Along the way, the ions involve in the process neutral molecules from the air, which fly through the lattice and create thrust. Such engines are silent and capable of lifting a certain useful weight, but, unfortunately, require significant energy reserves.

A flying prototype of an ion-powered platform was created in the laboratory of the university. The dimensions of the sides of the robot are 2 cm and the weight of the structure is 30 mg. Another 36 mg weighs the power controller of the emitting electrodes. The voltage on the electrodes reaches 2000 V, although the current strength is only 3,5 mA. 7 wires are connected to the experimental platform, through which power and control are carried out. The principle of control is simple - one of the four arrays of electrodes is turned off in the required sequence, after which the tilt and movement in the desired direction occurs.

In the future, scientists plan to improve the platform to complete autonomy of control, with the exception of power. In the foreseeable future, none of them are waiting for the appearance of sufficiently powerful, capacious and miniature autonomous power supplies to be placed directly on the platform. But control can be given to the robot, for which it is planned to create a special controller and equip the robot with optical and other sensors.
