The future development trend of current sensors has the following characteristics:
1. High sensitivity. The intensity of the detected signal is getting weaker and weaker, which requires the sensitivity of the magnetic sensor to be greatly improved. Applications include current sensors, angle sensors, gear sensors, and space environment measurements.
2. Temperature stability. More application areas require more and more harsh working environments of sensors, which requires magnetic sensors to have good temperature stability, and industrial applications include the automotive electronics industry.
3. Anti-interference. In many fields, there is no comparison of the sensor environment, and the sensor itself is required to have good anti-interference. Including automotive electronics, water meters and more.
4. Miniaturization, integration, and intelligence. To achieve the above requirements, this requires chip-level integration, module-level integration, and product-level integration. 5. High frequency characteristics. With the promotion of the application field, the working frequency of the sensor is required to be higher and higher, and the application fields include the water meter, the automobile electronics industry, and the information recording industry.
6, low power consumption. Many areas require the sensor itself to have very low power consumption to extend the life of the sensor. Applied to magnetic biochips, compasses, etc. implanted in the body.
