Elder Care Based on Cognitive Sensor Network

The advancement of semiconductor fabrication technology and smart algorithms has allowed us to design and develop intelligent sensors with cognitive ability. Statistics reveal that in recent times the number of elderly people is increasing rapidly around the world and the situation is not going to ease in the foreseeable future. In this paper, we report a novel home monitoring system which is based on cognitive sensor network and is intended for elder-care application. The smart system consists of an optimum number of cognitive wireless sensors which are used to detect usage of electrical devices, bed usage pattern, flow of water, etc., and also incorporates a panic button. The cognitive sensors provide information that can be used for monitoring the elderly by detecting any abnormality pattern in their daily activities around the house. The system will generate and send an early warning message to the care giver, when an unforeseen abnormal condition occurs.

Necessity of a bed-sensor in a smart digital home to care for elder-people

We are exploring the development of a smart digital home based on wireless sensors. The wireless sensors have more advantages when compared with the wired sensors as they are more flexible, portable, can be used in different places to remote monitor the various activities remotely. They even consume less power depending on their operation. Based on this technology a system has already been developed consisting three wireless sensors; these sensors detect use of electricity when the target appliances are connected to mains supply. But it has been realized that there is a requirement of a few more sensors to make a smart home monitoring system. This paper has reported the development of a bed-sensor which forms one of the sensors of the intelligent home monitoring system.

But with increased of age mental abilities are reduced and there is a necessity of caregiver which may interfere with their privacy. In this research work, we target towards the development of a wireless sensors based home monitoring system especially for elder people. The current system is based on sensors which detect use of electrical appliances whether they are connected to electrical mains. But it has been realized to there is a requirement of a few more sensors to making a smart home monitoring system. This paper has reported the development of a bed-sensor which forms one sensor of the home monitoring system.

Intelligent bed sensor system: Design, expermentation and results

This paper presents the design of an intelligent bed sensor that is part of a larger smart home monitoring system for the elderly. The sensor sub-system not only detects the mere presence of a person on the bed, it can precisely indicate the persons position on the bed. Initial test results are promising and it is envisaged that the sensor system will be extended to detect abnormalities in sleeping pattern such as sleep-wake periods, restlessness etc. The system is built around four force sensors installed at the base of the four bed posts. The paper reports the initial load test results using 25 lbs sensors on a table. Extrapolating techniques have been proposed and utilised to calculate the precise location of the load on the table.

Determination of sleep quality of inhabitant in a smart home using an intelligent bed sensing system

There are many issues in designing and implementing an intelligent wireless sensor network based smart home for monitoring the elderly. The smart home is based on a few smart and intelligent wireless sensors, which can be configured around a wireless ad-hoc network. The system will generate early warning message to care giver, when an unforeseen abnormal condition occurs. The costs and risks associated with system also dictate that unnecessary components be filtered from the systems design; therefore, all sensors in the network must justify their existence and purpose of the system. An intelligent bed sensing system is very important to determine the quality of sleep of the inhabitant in the smart home. The paper has proposed an intelligent bed sensing system and trial results are presented.
