PPG is a non-invasive optical method that provides information about the pulsatile component of blood flow. It involves illuminating the skin with a light source, usually a light-emitting diode (LED), and detecting the reflected or transmitted light using a photodetector. Moreover, advancements in sensor technology, miniaturization and low-power electronics have contributed to the development of PPG biosensors. These advancements have led to the integration of PPG sensors into smaller, wearable medical devices that offer improved accuracy, reliability, and battery life.

Furthermore, the market is primarily anticipated to increase due to the rising prevalence of cardiovascular diseases (CVD). For instance, in 2022, according to the Centers for Disease Control and Prevention (CDC), approximately 699,659 deaths occurred due to CVD in the U.S. Thus, the combination of this technique with technological advancements appears to proportionately increase the speed of cardiopathies' detection, improve medical care through remote patient monitoring and control and thereby reducing the number of CVD-related deaths. In addition, compared to electrocardiogram (ECG) sensors, PPG is a non-invasive, affordable method that can measure the signal at a variety of locations, including the fingers, toes, ears, wrists, chest, and heads.
