Demographic developments, social changes, and the rising costs of health and social care due to people with chronic disease, people with mobility limitations and elderly population make necessary to rethink care delivery. A practical way to improve care and cut healthcare costs is to develop integrated electronic health (e-health) solutions that permit monitoring of physiological parameters and motor activities of the users in their homes.
The unobtrusiveness and non-invasiveness of biomedical measuring devices are key factors on acceptance and satisfaction from the subjects in e-health context. This is justified taking into account that through unobtrusive and non-invasive measurements the data on user’s health status may be obtained with or without interactions between subject and biomedical monitoring system.
Unobtrusive cardiac and respiratory activity monitoring remains a challenging task. This chapter is dedicated to a review of unobtrusive biomedical sensing solutions with higher capability in integration on ubiquitous healthcare systems. Elements of signal processing associated with health status measuring channels are included in this chapter.
