FSR Medical Mattress Pressure Monitoring System

System Overview

The FSR Medical Mattress Pressure Monitoring System adopts flexible thin-film pressure sensing matrices embedded inside care mattresses. The system collects real-time multi-point pressure distribution data on the mattress surface, identifies the patient’s posture, bed exit, in-bed and prolonged sitting status, and generates pressure heatmaps. Data is uploaded to the monitoring terminal for pressure ulcer risk early warning, bedridden patient status tracking and smart ward management. Featuring ultra-thin and flexible design, the system will not compromise mattress comfort. It is compatible with various medical care beds and widely deployed in hospital wards, elderly care facilities and rehabilitation centers.

How does it work?

The resistance of FSR force-sensitive resistors decreases as applied pressure increases. When a person lies on the mattress, pressure is transmitted to the embedded FSR sensor array. The main acquisition unit scans all sensing pixels row by row and column by column, collects pressure signals of each point. After filtering and noise reduction, the algorithm analyzes the pressure distribution map to judge the patient’s lying posture, bed-exit status and local high-pressure areas. Monitoring data is transmitted to the host terminal in real time to realize pressure ulcer risk alerts and patient status alarms. Without applied pressure, FSR sensors return to a high-resistance state, indicating no person on the bed.
