Close to the photoelectric beam sensor products use the transformation function of various materials to achieve the purpose of information or energy conversion and detection. Various functional materials are the material basis for the development of sensor technology. In addition to research principles, the development and development of new sensors depend to a large extent on new materials. The materials used in the production of sensors have the following requirements: large conversion function (effect), wide sensing range, high sensitivity and precision, good stability and reproducibility, small size, simple structure, and long service life.

In modern photoelectric beam sensor products, precious metal materials, semiconductor materials, functional ceramic materials and functional polymer materials are mostly used. Among them, metal materials are functional materials that are more suitable for making traditional photoelectric beam sensor products, and their applications range from the sensitive structure of structural sensors to the parameter measurement elements of physical sensors.
The photoelectric beam sensor of semiconductor materials is an important material basis for the manufacture of various sensors. Its application opens up a broad prospect for the miniaturization, digitization and high precision of instruments. The photoelectric beam sensor products based on semiconductor materials not only have high sensitivity, fast response speed, and small size. Lightweight, and easy to realize the integration and multi-function of the sensor. Semiconductor photoelectric beam sensor products have become the current heavy technology development field, and are currently developing in the direction of integration, functionality, and intelligence.
