The functionality of consumer wearables

A summary of the functionality of selected digital wearable devices.

Overview

I recently had a look into the functionality of consumer wearables to understand the state-of-the-art. This post summarises the findings, and further details are provided in the following book chapter: Wearable Photoplethysmography Devices.
