Measurement of Vital Signs with Non-invasive and Wireless Sensing Technologies and Health Monitoring

摘要

Medical treatment and health service is one of the basic needs for every human being. People tend to get services from physicians and clinics. Although medical service is supposed to be available and easily accessible, in the third world countries, it is rare and expensive to get this service easily everywhere and at any time. Mass people have also less idea about medical measurements. In particular in the third world countries medical practitioners are not available in remote areas. Hence, remote health and patient monitoring is important to provide the under privileged people easy health monitoring technologies and the freedom to be health-conscious. This research on remote health monitoring leads to development of technologies, which can be used by anyone for health check-up. The technologies researched here lead to making of useful devices and applications, which are very easy to use, less, expensive, and with the capability of monitoring health conditions remotely. This research includes remote health monitoring for technologies e.g. Spirometry, heart rate measurement, Body Mass Index measurement, and instant skin temperature measurement. We implemented these technologies using basic circuits and developed Android based application. The implemented hardware is interfaced wirelessly with an Android phone where the app provides the measured vital signals to the user. We evaluated our system by comparing the measured values with the values got from the standard medical devices and the results are found to be very close to accurate values.
