Abstract
The invention relates to the technical field of vehicle seat systems, in particular to a seat capacitance sensor based on conductive fabric and a measuring method. The seat capacitive sensor based on conductive fabric is characterized in that an upper layer and a lower layer of a non-woven fabric felt layer are respectively connected with a first conductive fabric layer and a second conductive fabric layer by using a binder; the first conductive fabric layer and the second conductive fabric layer are formed by plating copper or nickel on fiber cloth through an electroplating process, and the thickness of the first conductive woven fabric layer and the second conductive woven fabric layer is less than 2mm; the thickness of the capacitive sensor is less than 4mm; and the area of the first conductive weaving layer is smaller than that of the non-woven fabric felt layer and that of the second conductive weaving layer. Compared with the prior art, the capacitive sensor which is light, soft and low in cost is designed by utilizing the characteristics of the conductive fabric, and the capacitive sensor is applied to the automobile seat, so that the state of the automobile seat can be adjusted in real time according to the posture of a passenger, and the overall comfort of the automobile seat is improved.
