The compact device will help to detect diseases of the brain and heart more precisely ECG and EEG

Employees of MIPT and the V. A. Kotelnikov Institute of Radio Engineering and Electronics (IRE) of the Russian Academy of Sciences have created a high-sensitivity dimensional detector that can detect magnetic radiation of different ranges. The development has important practical applications. This includes the production of miniature and inexpensive devices for magnetic encephalography and cardiography.

The phenotype of that: scientists will increase the accuracy of diagnosis of heart failure

How will the new method make it possible to better predict and treat a dangerous disease?

Such studies significantly exceed the accuracy of electroencephalography (EEG) and electrocardiography (ECG), which are familiar to everyone, but now they remain experimental, since the necessary equipment functions only at ultra-low temperatures. As a result, these are cumbersome and expensive installations. Specialists have already started developing the device based on new principles.

"Organs, such as the brain and heart muscle, generate electromagnetic impulses. But the power of the magnetic fields is very small. Our detector can register them and monitor the condition of these organs. ECG and EEG measure the electrical component of the heart and brain. But the magnetic component is much more accurate, due to the fact that it comes directly from these organs. Therefore, magnetic encephalographs and cardiographs are more effective. However, existing devices are too bulky for this, as they are installed in cryostats. And they are very expensive. We are creating sensors that work at room temperatures," said Sergey Nikitov, Head of the MIPT Department of Electronics and Director of the IRE RAS.

The new detector is slightly more than 100 nanometers thick. The main components of the device are a thin film of lutetium garnet and a layer of platinum.

The detector's wide frequency range, ultra-low power consumption, and compatibility with silicon technologies will help create tiny and lightweight communication modules for space satellites, radars for drones, and elements for quantum electronics in the future, Sergey Nikitov added.
