With the rapid growth of a number of elderly people around the world, an increasing need has arisen in providing physical security to them. Researchers have been working in developing such monitoring systems for the past decades. However, the needs of elderly people and their families are yet to be fulfilled, especially since the developed existing systems need their users to change their lifestyles. This work aims at suggesting a system for monitoring the occupancy of an elderly person on the bed. Capacitive proximity sensing system has been proven to be a probable solution for indoor localization, which senses the presence of a human body. Nevertheless, the requirements for installation are many, which make the integration costly. In this paper, a flexible and integrated solution is proposed that makes use of inexpensive, open source hardware, allowing indoor localization and fall detection. The bed monitoring system is made up of aluminum sheets sensor electrodes installed under the bed sheets to detect the sleeping patterns of the subject. An alarm system has been integrated into the room to enable the elderly to call for help during an emergency. Presence detector and light controlling device are installed on the floor surface to detect the mobility of the elderly and turn ON/OFF the room lights automatically. The proposed system allows elderly people to live independent living at homes with all amenities.

“…The purpose of this system was to stop a robot moving to ensure the safety of any person who came too close to it. Two years later after Karlsson's 'person detector', Thomas Zimmerman et al from MIT Media Laboratory presented various ideas on capacitive applications in [56], including a two-dimensional Finger-Pointing Mouse and a Person-Sensing Room. The floor of the Person-Sensing Room was covered by a transmitting electrode and four receiving electrodes were placed on the walls.…”

“…In contrast to the systems of Karlsson [13] and Zimmermann [56], the electrode arrangement in these studies consists of a segmented floor composed of multiple transmitters and one or more receivers placed in the vicinity of the transmitters. The segmented floor in all of these studies was built from raised floor tiles that had a conductive metal layer on the bottom surface of the tile (see Figure 2).…”

Abstract. Sleep disorders are a wide-spread phenomenon that can gravely affect personal health and well-being. An individual sleep analysis is a first step in identifying unusual sleeping patterns and providing suitable means for further therapy and preventing escalation of symptoms. Typically such an analysis is an intrusive method and requires the user to stay in a sleep laboratory. In this work we present a method for detecting sleep patterns based on invisibly installed capacitive proximity sensors integrated into the bed frame. These sensors work with weak electric fields and do not disturb sleep. Using the movements of the sleeping person we are able to provide a continuous analysis of different sleep phases. The method was tested in a prototypical setup over multiple nights.
