During the 2023 World Manufacturing Congress, CIQTEK launched the self-developed "Atomic Magnetometer (SpinMag-I)", a commercial Atomic Magnetometer with low energy consumption, easy to carry, and extremely high magnetic field sensitivity, which can be used for precision measurements of cardiac, cerebral, and geomagnetic magnetic fields, with the 100,000-fold increase in sensitivity compared with the classical technology (Hall effect sensors), and is expected to breed new changes in the fields of biomedicine, industrial detection, and geophysics. Opening Ceremony of the World Manufacturing Congress 2023   Atomic Magnetometer（SpinMag-I） Atomic Magnetometer（SpinMag-Ⅰ） The Atomic Magnetometer (SpinMag-I) takes advantage of the spin nature of the outer electrons of alkali metal atoms (Rb-87) and uses a pump laser as a means of manipulation to spin-polarize the alkali metal atoms. Under the action of an external weak magnetic field, the alkali metal atoms undergo Larmor progression, changing the absorption of the detection laser, thus realizing highly sensitive magnetic field measurements. The Atomic Magnetometer is characterized by high sensitivity, small size, low energy consumption, and easy portability, which will lead mankind to enter the field of magnetic sensing in scientific research, biomedicine and other fields in the future. For very weak magnetic measurements, help cardiac and brain magnetic imaging research The detection sensitivity of SpinMag-I is less than 15 fT/√Hz. The advantage of high sensitivity leads to unique applications, the most prominent of which is currently biomagnetic imaging (brain and cardiac magnetism). Magnetic brain research equipment. Image from the web.   Brain magnetism is caused by the spontaneous or induced activity of a population of brain cells, which generates a complex biological current. This signal can be captured by SpinMag-I and reconstructed to form a mathematical image according to a certain mathematical model, thus obtaining the person's brain magnetic image. Magnetic brain imaging can be used for screening of functional diseases such as epilepsy, Parkinson's, Alzheimer's, etc., and has a lower cost compared to current magnetoencephalography based on superconducting interferometer technology (SQUID). Meanwhile, the Atomic Magnetometer also provides more technological means for cutting-edge research in brain science such as brain-like computing and brain-computer interface. SpinMag-I can also be used for cardiac magnetic measurements for functional diagnosis and research of cardiovascular diseases such as myocardial ischemia. Cardiac magnetic testing based on this method has the advantages of being non-invasive and radiation-free, and is safer than current ultrasound, CT, and nuclear magnetic methods.   Product Features Miniaturization SpinMag-I probe size is approximately 30 x 16 x 12 mm3 and continues to evolve towards miniaturization. This is due to the fact that miniaturized pro...
