Maximizing Power in Wearable Heart Monitors

Measuring multiple parameters, accurate readings, and having a long battery lifetime: these are the most critical parameters for a wearable device that monitors cardiovascular health. Wearable devices that were initially meant for sports and wellness purposes are now being designed for medical purposes, measuring critical health parameters such as heart rate and heart rate variability (HRV). With this transition, the accuracy of the measurements and device's battery lifetime become more important design considerations. This article examines this new generation of wearable health devices, including how to make a system more reliable and more power efficient.
