4.2 Heart Rate Detection
Heart rate detection is an optical measurement technique that uses a light source and a detector to detect cardiovascular
pulse wave that propagates through the body. The detected signal (pulse wave) called photoplethysmography and it is
known as PPG/PTG. The PPG signal reflects the blood movement in the vessel, which goes from the heart to the fingertips
through the blood vessels in a wave-like motion. Therefore, we can use this PPG signal to calculate heart rate.
This optical based technology could offer significant benefits in healthcare application as it is noninvasive, yet accurate and
simple to use.
