Abstract: A distance adjustment apparatus and a control method of the distance adjustment apparatus are provided. The distance adjustment apparatus includes a connection component, and the connection component includes a first component and a second component. The first component is connected to the second component, and a memory alloy component is disposed in a connection region between the first component and the second component. The memory alloy component is controlled by a current to drive the first component and the second component to move closer to and/or away from each other.

Abstract: A haptic sensing device, including a light source, an optical waveguide, a photoelectric sensor, and a housing. The optical waveguide includes a waveguide layer and a cladding, the cladding encloses the waveguide layer, and a refractive index of the waveguide layer is greater than a refractive index of the cladding. The waveguide layer includes a plurality of paths, the light source is disposed at an input end of each path, and the photoelectric sensor is disposed at an output end of each path. The light source, the optical waveguide, and the photoelectric sensor are accommodated in the housing. A plurality of contacts are distributed on the housing. When a contact is pressed, the contact is in contact with one path, and the path is deformed. When any two contacts are pressed, the two contacts are in contact with different paths.

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.
