As shown in fig. 1, the cloth-based pressure-sensitive mattress structure includes: layers 1 and 3 (i.e., the first facing layer and the second facing layer) are textile facing layers at which the pressure sensor is textile formed, and layer 2 is an intermediate layer that may include latex, breathable material, or a spring support structure.
As shown in fig. 2, the textile pressure sensing working principle is as follows: sn and Dn form electrode plates with capacitors facing up and down, the electrode distance is d, the electrode shape is constant, the size of the formed inter-plate capacitor Cnn and the inter-plate distance d are in inverse proportion, when F pressure acts on one electrode plate, the distance d becomes small, the capacitance value Cnn becomes large, and the size and the position of the F pressure can be calculated by detecting Cnn size through a micro-processing unit.

2) According to the capacitance value calculation formula Cnn ═ K × S/d (K is the dielectric constant of the pressure sensitive material, S is the facing area of the two layers of electrodes Dn and Sn, and d is the distance between them), the dielectric constant K is determined by the material, and the facing area S is determined by the design and has a directional relation with the distance d.
3) Regarding the relationship between the parallel plate capacitance distance d and the pressure F, when pressure F is applied, the distance d becomes smaller and the parallel plate capacitance Cnn becomes larger, whereas when k and S are constant, the magnitude of the capacitance Cnn is determined by the pressure F, the pressure F increases and the corresponding capacitance Cnn also increases.
4) The principle of pressure detection is to detect the relative magnitude of the pressure-sensitive force F by measuring the change in magnitude of the capacitance Cnn. In the initial state, the pressure sense corresponding to the node capacitance Cnn is defined as zero in the absence of pressure, and the node capacitance Cnn corresponding to the maximum pressure F is defined as maximum. After the maximum Cnn value is divided, the divided area corresponding to the pressure F can be calculated as the relative magnitude of the pressure.
5) The above Cnn represents the node capacitance at a certain position on the pressure-sensitive mattress, n × n intersections of the driving and sensing electrode row arrays form n square nodes, and the set of n square capacitors can be detected, which represents the set of detected pressure-sensitive sizes of the whole surface of the pressure-sensitive mattress.
