Published in the prestigious journal Nature Communications, the technique works on a microchip scale and – unlike other common approaches – does not require the input of a laser.

Most existing quantum sensing and magnetic field imaging devices are relatively large and expensive, requiring optical pumping (from high-power lasers) or very low cryogenic temperatures. This limits the device integration potential and commercial scalability of this approach.

In contrast, the OLED sensing device prototype in this work will eventually be small, flexible and mass-producible.

The technologies involved in achieving this goal are electrically detected magnetic resonance (EDMR) and optically detected magnetic resonance (ODMR). This is achieved using cameras and microwave electronics to optically detect magnetic resonance, the same physics that enable magnetic resonance imaging (MRI). Using OLEDs for EDMR and ODMR depends on correctly exploiting the spin behavior of electrons when they are in proximity to a magnetic field.

OLEDs, which are highly sensitive to magnetic fields, are already appearing in mass-produced electronics such as televisions and smartphones, making them an attractive prospect for commercial development among new technologies.

Professor Dane McCamey of UNSW, who is also Exciton Science’s lead researcher, said: “Our device has been designed to be compatible with commercially available OLED technology, offering the unique ability to map magnetic fields over large areas and even curved surfaces.

“You could imagine using this technology being added to a smartphone to aid in telemedicine diagnosis, or to identify defects in materials.”

Lead author Dr Rugang Geng, from UNSW and Exciton Science, added: “While our study demonstrates a clear technical pathway, more work is needed to improve sensitivity and read times.”

Professor McCamey said a patent had been applied for (Australian patent application 2022901738) with a view to potential commercialization of the technology.

Recent reports have shown that Microsoft Xbox has written its name down in the books of history. Currently ranking as the bestselling gaming console, the Xbox has taken down competition from PS5 and the Nintendo Switch. This is a new improvement in the world of gaming and sure Xbox lovers will have something to brag about. But for how long will the Microsoft Xbox hold its number one position?

For a long time now, the Nintendo gaming consoles have been occupying the best selling console position. They have been sitting comfortably at the top with no lasting threat posed by any rival. Nintendo has its pricing and affordability to thank for its success. But a new king reigns now!

The first quarter of sales in the year 2022 saw the Xbox rise in its hardware sales and overtake the Nintendo Switch. The most recent Xbox console, the X/S sold 4.5 million more than what the previous model sold. The impressive sale of the Xbox series is the very reason behind the Xbox being named the bestselling console in the first quarter of 2022.

Can the Xbox try as much as possible to remain the world’s best-selling console despite the stiff competition that it’ll face in the gaming market? The pricing of these gaming consoles are quite similar to the competition. The Xbox series X sells at a retail price of $499 while the not so specs Xbox series S sells at a retail price of $299.

The Xbox’s most recent series has proved to be the new generation of console and sort out yourself. Microsoft’s move to produce its very own games and make them exclusive for Xbox consoles could have further boosted the sales of the Xbox. We will keep an eye out on the gaming news and releases space to see how long Xbox will hold on to its title as the bestselling gaming console.
