1. High frequency characteristics. With the promotion of application fields, the working frequency of sensors is required to be higher and higher, including water meters, automotive electronics industry, and information recording industry.

2. Low power consumption. Many fields require sensors to have extremely low power consumption, and powerful magnets can extend the lifespan of sensors. Applied in implanting magnetic biochips, compasses, and more into the body.

3. Clean once a half month, and the benefit of cleaning is that it can ensure the temperature stability of the magnet factory. More application fields require increasingly harsh working environments for cutting magnets in sensors, which requires magnetic sensors to have good temperature stability. Industry applications include the automotive electronics industry.

4. Controlling the timing of lucky work can achieve anti-interference. There is no evaluation of the usage environment of sensors in many fields of powerful magnets, which requires the sensors themselves to have good anti-interference performance. Including automotive electronics, water meters, and so on.

5. Miniaturization, integration, and intelligence. To achieve the above requirements, powerful magnets require chip level integration, module level integration, and product level integration.
