Problems solved by technology

[0003] (1) During the fingerprint detection process, it is necessary to collect and compare the fingerprints through the fingerprint sensor. There are many kinds of fingerprint sensors. As far as the detection device with a semiconductor fingerprint sensor is concerned, it is easy to sweat when detecting in high temperature weather or the person to be verified, so the finger Sweating, because the finger needs to be in contact with the surface of the semiconductor fingerprint sensor during fingerprint collection and detection, so the sweat will stay on the semiconductor fingerprint sensor, and the sweat contains salt, which will erode the surface of the semiconductor fingerprint sensor, which will cause the semiconductor fingerprint sensor to fail. There is generally a coating on the sensor, but as the number of uses increases, the coating will gradually be eroded, which will affect the efficiency and accuracy of fingerprint detection;

[0004] (2) When testing in wet weather, the surface of the semiconductor fingerprint sensor is relatively wet. Because water is oriented, it will affect the electric field of the semiconductor fingerprint sensor, which will lead to incomplete fingerprint collection, resulting in the need for multiple collections and detections. A situation where detection cannot be performed occurs
