Integrable electronic system for pulseoximetry/heartbeat detection

An integrated pulseoximeter/heartbeat rate detector is herewith described. The ready-to-use capability and its easy portability make the device a reliable, non-intrusive detector to be used in a large amount of applications (medical, domestic monitoring, sport scenarios). Both the blood oxygen percentage detection (i.e. pulsoximetry) and heartbeat rate monitoring are obtained thanks to a light-sensible set of diodes and receivers, by opportunely evaluating the emitted and received power light ratio through the body, using a standard technique. Test results have demonstrated that a simple 10-bit A/D converter can display both the O2 blood concentration percentage and the heartbeat rate accurately.
