This paper proposes a safety confirmation system consisting of a mat sensor and a power line communication device that can be installed in small-sized senior citizen welfare facilities without a nurse call and in ordinary households. The proposed system detects when a senior citizen attempts to get out of bed or leave a room, sending an alarm to the control room or a caregiver in another room. The power line communication enables such housing facilities to set up safety confirmation easily and inexpensively. The usefulness of this system has been verified by field examination in the senior citizen welfare facility.
