Wearable photoplethysmographic sensors—Past and present
Electronics. 2014;3:282–302
TL;DR
A review of the history of PPG and of wearable pulse-rate sensors. It covers infrared LED/photodetector designs and the move to high-intensity green LEDs that made wrist PPG practical, and discusses where wearable pulse-rate monitors are used.

Abstract
Photoplethysmography (PPG) technology has been used to develop small, wearable, pulse rate sensors. These devices, consisting of infrared light-emitting diodes (LEDs) and photodetectors, offer a simple, reliable, low-cost means of monitoring the pulse rate noninvasively. Recent advances in optical technology have facilitated the use of high-intensity green LEDs for PPG, increasing the adoption of this measurement technique. In this review, we briefly present the history of PPG and recent developments in wearable pulse rate sensors with green LEDs. The application of wearable pulse rate monitors is discussed.
