Problems solved by technology

[0002] Existing sensors are expensive, require high machining accuracy, high cost, and complex structures. The more sensitive the sensor, the easier it is to sense small environmental changes. The more sensitive the detection system is, the more conducive to the high-speed response of the equipment. The existing Highly sensitive sensors are very expensive
