We know that semiconductor sensors, whether capacitive or inductive, have similar principles. On a "flat plate" integrated with thousands of semiconductor devices, the finger on it forms the other side of the capacitance (inductance). Because the finger plane is uneven, the actual distance between the bump and the concave point contacting the flat plate is different, and the capacitance/inductance value formed is also different, According to this principle, the device collects different values and completes the fingerprint collection. The semiconductor fingerprint head can penetrate the surface layer of the skin, so the silica gel analog fingerprint widely circulated on the Internet basically does not play a role here. The advantage of identifying living fingerprints is that fingerprints can not be copied or imitated basically.
