Decubitus ulcers, more commonly known as bedsores, are a common and potentially serious problem for bedridden hospital patients. Swiss entrepreneur Michael Sauter thought the situation needed addressing, so he invented a bed that turns the patients over itself. Known for the time being simply as an intelligent bed, the device is said to imitate the movements of a healthy person during sleep. It does this by logging the patients movements as they sleep. If theyve stayed in one position for too long, it gently moves them, via a special mattress that lies on a joint-less but flexible slatted frame. That frame is reportedly made from smart materials, the properties of which can be adjusted as needed. The bed was developed through Swiss research institute Empa. GM
