An intelligent bed adaptively controlling body pressure distribution

Abstract

This study aims to develop an intelligent bed which can control body pressure distribution adaptively. This bed is actuated by multi-flexible bags. This bed is controlled by air pressure conjugated with a body simulator. This report describes basic experiments with multi-flexible bags and a fundamental body simulator. These bags realized high pressure resistance and we verified experiment of feedback control by using inner pressure sensors. For development of the body simulator, we examined a simple dynamic model to obtain body pressure distribution and body posture in lying position.
