Sensors based wearable systems for monitoring of human movement and falls

  1. 1. Sensors-Based Wearable Systems for Monitoring of Human Movement and Falls Abstract: The project focuses the applications for a rapid aging of the world’s population, along with an increase in the prevalence of chronic illnesses and obesity, requires adaption and modification of current healthcare models. One such approach involves tele health applications, many of which are based on sensor technologies for unobtrusive monitoring. Therefore, the current technological advances, in particular, involving microelectromechnical systems, have resulted in miniaturized wearable devices that can be used for a range of applications. One of the leading areas for utilization of body-fixed sensors is the monitoring of human movement. An overview of common ambulatory sensors is presented, followed by a summary of the developments in this field, with an emphasis on the clinical applications of falls detection; falls risk assessment, and energy expenditure. Existing System: The existing system is consists of a manual monitoring which possess more risking. The user’s privacy is not protected in previous wired or wireless sensor network. There are no wearable sensors for monitoring human movement and falls. This proves to be a major drawback in the existing system. So we go to our proposed system. Proposed System: This paper presents a monitoring for healthcare system, which focuses on summary of the development of this field. The wearable sensors consist of accelerometer which has been placed in the patient body to sense the acceleration along a sensitive axis and over a particular range of frequencies. The sensor value is send to the controller, and that will intimate an alarm if the person falls down which sensed by the accelerometer. The temperature also monitored of the person when its level increased above the normal level. The status will be shown in LCD.
