Exactly what you need – high efficiency and high diversity
Along with the "Quantified Self Movement" gaining popularity, there is an increasing interest in medical measurement methods that can be integrated in so-called wearable gadgets such as watches, smart phones or fitness bracelets. It started with fitness trackers determining the step frequency by using acceleration sensors. Now optical sensors expand the possibilities of self-observation, as they also offer a straightforward measurement of the heart rate and oxygen saturation of the blood. In addition, the pulse measurement on the wrist is much more convenient than, say, wearing a chest strap. Last but not least optical methods score in economic terms as well, as the new technologies for highly efficient LEDs allow for more energy-efficient and compact sensors.
