Abstract
A capacitive sensor, an electronic device, and an electronic device control method are disclosed and relate to the field of sensor technologies. The capacitive sensor includes at least one plate pair. Each plate pair includes a first plate and a second plate that are placed opposite to each other. A ratio of a plate length of each plate pair to a spacing in the plate pair is greater than 1 and less than or equal to 30. The capacitive sensor can detect an air gesture of a user based on fringe field effect and has advantages of a small size and low energy consumption.
