Did You Know About the Development Trend of Magnetic Field Sensors?

The future development trends of magnetic field sensors have the following characteristics

High sensitivity

The detected signals are becoming weaker and weaker, which requires a significant improvement in the sensitivity of the cylinder magnetic sensor. Applications include current sensors, angle sensors, gear sensors, and space environment measurements.

Temperature stability

More magnetic field sensor applications areas require the working environment of magnetic field sensors to be increasingly harsh, which requires magnetic field sensors to have good temperature stability. Industry applications include the automotive electronics industry.

Anti-interference

In many fields, magnetic field sensors are used in environments without any shielding, which requires magnetic field sensors to have good anti-interference capabilities. This includes applications in automotive electronics, water meters, etc.

Miniaturization, integration, and intelligence

To meet the above requirements, chip-level integration, module-level integration, and product-level integration are required.

High-frequency characteristics

With the promotion of application areas, the working frequency of magnetic field sensors is increasing, including applications in water meters, the automotive electronics industry, and the information recording industry.

Low power consumption

Many fields require magnetic field sensors to have extremely low power consumption in order to extend the service life of magnetic field sensors. Applications include magnetic biological chips implanted in the body and electronic compasses.

The wide range of applications of magnetic field sensors

Magnetic field sensors are widely used and play an important role in the national economy, national defence construction, science and technology, and medical health fields. They have become a major branch of the modern sensor industry. In traditional industrial applications and transformation, resource exploration and comprehensive utilization, environmental protection, bioengineering, intelligent traffic control, and other aspects, they play an increasingly important role.

Among all end-user industries, the consumer electronics industry has the fastest growth rate in the market for magnetic field sensors. Magnetic field sensors are widely used in various devices from small consumer electronic devices to large household appliances. The digital magnetic sensor is used in electronic consumer devices such as smartphones, laptops, tablets, DVD players, printers, cameras, and large devices such as washing machines. They are also widely used in smartphone navigation because every smartphone is equipped with a global positioning system (GPS) system.

The automotive and consumer electronics industries are the largest end-market for magnetic field sensors, accounting for about 90% of the market share. The market and production of these two parts are shifting to China, and Chinese companies face huge development opportunities. As the most grounded country in the field of magnetic field sensors, China is closer to the market, closer to demand, and can respond to market demands faster. In the future, magnetic field sensors can cover every corner of industrial, military, and medical applications, with huge market space. The growth of the magnetic field sensor market and the rise of emerging applications are attracting new manufacturers to enter the supply chain, thereby influencing and changing the competitive landscape.
