IKEA Qi wireless charger

23.09.2021

IKEA has unveiled a device called the Sjomarke, which is a built-in Qi wireless charger that can easily upgrade almost any table or shelving unit.

A couple of years ago, IKEA started selling furniture with built-in wireless chargers, and in 2019, in collaboration with Xiaomi, they released a table that supports 20W wireless charging. Now the Swedish furniture giant has decided to add wireless charging to its range to modernize old furniture.

The Sjomarke device can be easily hidden under the surface of a table or cabinet - it can be fixed both with double-sided tape and with self-tapping screws. Any non-metallic surface with a thickness of 8 to 22 millimeters will do.

The novelty is compatible with the Qi 1.2.4 protocol and provides power up to 5 watts. Also, the device is equipped with an LED charging indicator and a temperature and power control system for safety. The kit includes a two-meter power cable and a transparent sticker "X" to indicate the charging location on the surface.

The IKEA Sjomarke Wireless Charger will go on sale at IKEA in October for a suggested price of $40.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Controlling things with the power of thought 09.06.2022

Now telekinesis, the movement of objects with the power of thought at a distance, is in the minds of many something from the realm of science fiction. But Chinese scientists are actively working to make this phenomenon a reality.

Scientists at the China Air Force University of Engineering have taken the first step towards remote control of metamaterials using human brainwaves in a new study.

Metamaterials are man-made materials that have unusual physical properties, including electromagnetic properties, that do not occur naturally. The two-dimensional analog of metamaterials are metasurfaces, which have unprecedented freedom in controlling electromagnetic waves. According to scientists, it is possible to create programmable metasurfaces with different functions that can be controlled remotely using the human mind.

It is well known that the human brain creates brain waves in the process of thinking. Scientists have suggested that with the help of brain waves, which can be used as signals, you can control and control your metasurface mind.

During the study, Chinese scientists managed to achieve remote control of the metasurface through the transmission of human brain waves to a special receiver. Scientists wanted to make sure that a person can control the electromagnetic reaction of a programmable metasurface. And they were able to achieve this by demonstrating user control of the metasurface electromagnetic wave dispersion mode.

The results of the experiment showed that with the help of brain waves, a person more effectively controlled the functions of the metasurface at a distance than with the help of devices manually. Now, scientists plan to continue to conduct similar experiments in order to improve the quality of control over the metasurface with the help of the human mind.

Scientists believe that mind control at a distance can really be applied to various metasurfaces, including this method of control and management can be applied to monitor the state of human health, to transmit data in 5G and 6G communication generations and other areas.
