Abstract: This disclosure relates to a sensor, a sensing device, and a sensing method. The sensor may include an upper electrode layer, a dielectric layer, and a lower electrode layer. A first dielectric layer surface of the dielectric layer may be attached to a first upper electrode surface of the upper electrode layer. A second dielectric layer surface of the dielectric layer may be attached to a first lower electrode surface of the lower electrode layer. The second dielectric layer surface may be opposite to the first dielectric layer surface. The upper electrode layer may include at least two sub-upper electrodes arranged in an array. An electrode gap may exist between the at least two sub-upper electrodes.

Abstract: Disclosed are a vehicle floor, a body-in-white and a vehicle. The vehicle floor includes: a front floor and a rear floor provided in sequence from a vehicle head to a vehicle tail of a vehicle body, and a connecting assembly. The rear floor includes a first area obtained through a fixed mold and a second area obtained through a variable mold, and the second area of the rear floor is connected to the front floor. The connecting assembly is provided on the second area of the rear floor and is configured to connect to a battery pack of a vehicle, and a position of the connecting assembly on the second area is determined by a size of the battery pack and a wheel base of the vehicle body.
