The paper is organized as follows: in Section 2 applications
using kinematic sensors are presented, focusing on
actimetric, body posture monitoring and fall detection
applications; in Section 3 applications deploying the
embedded camera are discussed, focusing on blood
pressure, heart rate monitoring, blood oxygen saturation
measurement, and eye diseases recognition; in Section 4
applications using microphone for cough and breath sound
analysis are described; in Section 5 fundamental remarks
are argued with portrait of future developments; the
conclusions follow.
