The future development trends of magnetic sensors have the following characteristics:
1. High sensitivity. The strength of the detected signal is getting weaker and weaker, which requires a significant improvement in the sensitivity of the magnetic sensor. The application aspects include current sensors, Angle sensors, gear sensors, and space environment measurement.
2. Temperature stability. More application fields require the working environment of sensors to be increasingly harsh, which demands that magnetic sensors must have excellent temperature stability. Industry applications include the automotive electronics industry.
3. Anti-interference property. In many fields, the usage environment of sensors has no shielding at all, which requires the sensors themselves to have excellent anti-interference performance. Including automotive electronics, water meters, etc.
4. Miniaturization, integration and intelligence. To meet the above requirements, it is necessary to achieve chip-level integration, module-level integration and product-level integration.
5. High-frequency characteristics. With the expansion of application fields, the working frequency of sensors is required to be higher and higher. The application fields include water meters, the automotive electronics industry, and the information recording industry.
6. Low power consumption. In many fields, the power consumption of sensors themselves is required to be extremely low in order to extend the service life of sensors. It is applied in magnetic biochips implanted in the body, compasses, etc.
