Development of intelligent integrated bedding system Transformable pillow and mattress with multiple flexible actuators

This study proposes an intelligent bedding system that actively changes its shape and stiffness with multiple flexible actuators. The proposed system provides mechanical conditions for comfortable sleep by feedback control. The system comprises air bag actuators, feedback control system and an individual body simulator. Authors plan to control the actuators on the basis of the body simulator, which calculates appropriate body support condition. To develop the simulator, this paper discusses a mathematical model of human body to obtain pressure distribution and posture in supine position. Devices of pillow and mattress with flexible actuators are also described.
