Samsung Privileged Health SDK
The Galaxy Watch is equipped with Samsung’s unique BioActive Sensor that drives the next era of digital health monitoring. First introduced on the Galaxy Watch4 series, the BioActive Sensor uses a single unique chip that combines three powerful health sensors — Optical Heart Rate, Electrical Heart Signal, and Bioelectrical Impedance Analysis — to deliver extensive readings that include heart rate and blood oxygen level.
What is Samsung Privileged Health SDK
The Samsung Privileged Health SDK is specialized for Galaxy Watch4 devices or later. It provides both raw sensor signal data from the Samsung BioActive Sensor and processed data with our differentiated features.
The SDK supports an improved health tracking capability to allow your applications to track the user's health data accurately with the accelerometer, raw ECG (Electrocardiogram), PPG (Photoplethysmogram), and heart rate including inter-beat interval. In addition, it provides more advanced health features such as the body composition measurement, to enable compelling use cases for health and fitness applications. The blood oxygen level and sweat loss after a running workout are also useful data to check a user's health status.
What you can do
A watch application using the Samsung Privileged Health SDK runs on a Galaxy Watch with Wear OS powered by Samsung. It will help users to monitor their overall health data and to provide an advanced healthy life. The SDK can be utilized in various fields such as fitness, remote patient monitoring, senior care, digital therapy, fatigue risk management, and corporate wellness.
What are the advantages
Let's review more advantages of the Samsung Privileged Health SDK.
Low watch battery consumption
The Samsung Privileged Health SDK's accelerometer data, PPG green data, and heart rate data are all received as a batching event. The SDK's batching operation gathers sensor data in an application processor without waking up the CPU and sends an event at specific periods to a watch application. This minimizes the watch's battery consumption and enables a watch application to track the user's status for the entire day.
Receiving raw sensor data
The accelerometer, ECG, and PPG green data are provided as raw data by the Samsung Privileged Health SDK. This is very useful to conduct various analyses and more in-depth research with your own algorithm.
Using Galaxy Watch specific features
Measuring the user's body composition, blood oxygen level, heart rate including the inter-beat interval, and sweat loss after a running workout is a feature specific to the Galaxy Watch. Using the Privileged Health SDK, your watch application can easily measure these data.
