“…To distribute pressure and alleviate the risk of pressure ulcers, proper positioning of the patient or the use of an overlay, such as an Alternating Pressure Air Mattress (APAM) or seat cushion, is necessary. These commercially available devices feature air cells that inflate and deflate, effectively redistributing pressure [6][7][8][9][10][11]. However, these devices operate based on the present system defined by the manufacturer and lack the ability to sense high-pressure areas.…”

This research focuses on developing an intelligent air mattress prototype based on commercially available alternating pressure air mattresses to prevent pressure ulcers. Force-sensitive resistors (FSRs) are installed under each air cell to measure interface pressure values occurring at different parts of the body. These collected values are then used to create pressure maps, indicating areas of high overpressure. The prototype incorporates a smart pneumatic control system divided into seven functional areas: head, back, waist, buttocks, thighs, calves, and heels. All operations are performed using LabVIEW software.
