ABSTRACT: Pressure ulcers are a common complication among
wheelchair-bound population. They are resulted from prolonged exposure to high
pressure, which restricts blood flow and leads to tissue necrosis. In this
work, a continuous pressure monitoring system is developed for pressure ulcer
prevention. The system consists of 64 pressure sensors on a 40×50 cm2 sheet. Real time pressure data and corresponding maps are displayed on a
computer simultaneously. Furthermore, a posture detection procedure is proposed
for sitting posture identification. Having information about the patient’s
postural history, caregivers are capable of a better decision about
repositioning and treating the patient.
