Supporting preventive medicine and health care
Ancona, September 2015. The symptoms and causes for different health problems reflect on several vital signals, like for example the heart rate and its variability, breathing, skin temperature and conductance, movement patterns, etc. and can be detected through biomedical sensors. The integration of such sensors together with a communication interface is known as a body-area network (BAN).
The acceptance of these sensor networks mainlhy depends on three main factors: (i) usage comfort and discretion, (ii) cost and (iii) energy consumption. Usage comfort and discretion is accomplished through sensor miniaturization and wireless communications, in such a way that the user can perform a normal activity and have a normal aspect during the monitoring. Cost reduction is a decisive aspect for large scale market deployment and therefore for the improvement in quality of life and the reduction of health costs. Fianlly, theses sensors use to have the requirement of running 24 hours between battery charges.
The work presents the development of a low cost electrocardiogram (ECG) mobile device dedicated to user stress monitoring and discusses the results obtained in different experiments. Currently, the work is being extended to incorporate through a similar technology other sensors to measure othe vital signasl relvant for the monitoring of daily activities and its influence in the user's sleeep.
