Description

Technical Field

[0001] The utility model relates to the technical field of magnetic field measurement, in particular to a rotary measurement device for cell magnetic field measurement. Background Technique

[0002] As the basic functional unit of the human body, the physiological activities and states of cells largely determine the overall health status and the occurrence of diseases. Studying the physiological activities of cells at different stages or under different drugs helps to understand the cell development mechanism and the drug action mechanism. Common detection techniques include optical microscopy, electrophysiological recording, and biochemical analysis, etc. Although they play an important role in cell research, they often require complex preparation processes and multi-step analysis. In contrast, the detection method based on magnetic field signals has the advantages of non-invasiveness, high sensitivity, and real-time performance. Therefore, exploring and developing cell magnetic field detection techniques not only has important significance in basic research but also shows broad application prospects in clinical diagnosis and treatment.

[0003] However, the existing solutions for magnetic field measurement place the cells to be measured in a magnetic shielding device and measure them through sensors.
