Air Mat Pressure Distribution Detection for Body State Determination

The air mat device is segmented into multiple independent air cells arranged in a matrix pattern, where each cell can independently detect pressure at specific body locations. This segmentation allows for detailed pressure distribution mapping across different body regions, enabling accurate determination of body states such as kyphosis and lower limb contracture while maintaining a manageable device structure through modular cell organization.

The invention transitions from one-dimensional or two-dimensional pressure sensing to three-dimensional pressure distribution detection by arranging air cells in a vertical matrix structure with multiple layers. This dimensional expansion enables comprehensive measurement of pressure at various depths and locations, significantly improving body state determination accuracy through multi-layer pressure data comparison.

The measurement system is divided into multiple independent pressure detection zones corresponding to different body regions (head, upper body, buttock, foot). Each zone contains air cells that independently measure pressure at their specific locations. This segmentation allows the system to capture comprehensive pressure distribution data across the entire body while keeping each measurement unit simple and manageable.

The air cell matrix structure serves multiple functions simultaneously: it detects pressure at numerous locations, maps three-dimensional pressure distribution, identifies different body regions, and determines various body states (kyphosis, contracture, etc.). This multi-functionality improves measurement precision without proportionally increasing system complexity, as a single matrix structure accomplishes what would otherwise require multiple separate measurement systems.
