Abstract

In this paper, we discuss about a design and implementation of a smart bed system in order to aid caregivers for nursing elderly patients who are not able to move about freely. A minimum number of pressure sensors are deployed underneath the mattress cover, while considering both peoples’ standard physical characteristics and the specific body parts of commonly bedsore occurred. A whole sensing area of a patient’s body is divided into three sections and each of them is monitored by a distinct module which operates independently for fault tolerant operation. The smartbed system can identify three types of the patient posture: supine and lateral (left, right) position.
