Smart health applications continue to be an expanding market that needs to account for high performance, low power and high integration in various medical solutions.

The pulse oximeter is a small electronic device that measures an individual's oxygen saturation level, or the oxygen levels in the blood. It is an important device used to monitor the health of individuals with any type of condition that can affect blood oxygen levels. Renesas’ Smart Oximeter with Mobile App is a turnkey solution that provides a full system reference design, medical level algorithm and mobile connectivity with reference apps. This super-low power solution has the ability to measure accurately even on the most difficult of human subjects.
