Samsung Health Sensor SDK

Galaxy Watch includes 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 data that includes heart rate and blood oxygen level.

What is Samsung Health Sensor SDK?

Samsung Health Sensor SDK is compatible with Galaxy Watch4 series and later models. It provides both raw sensor signal data from the Samsung BioActive Sensor and processed data with our differentiated features.

SDK supports health tracking capabilities that allow apps to track user health data using the accelerometer, raw ECG (electrocardiogram), PPG (photoplethysmogram), and heart rate, including inter-beat intervals.

In addition, it provides access to health features such as body composition measurement, enabling a wide range of health and fitness use cases.

Blood oxygen level and sweat loss data collected after a running workout can also be used to assess a user's health status.

Improving health tracking capabilities with Galaxy Watch

A watch application utilizing Samsung Health Sensor SDK runs on a Galaxy Watch with Wear OS powered by Samsung. It will help users monitor their overall health data and promotes an enhanced healthy lifestyle. The SDK can be applied in multiple health areas including fitness, remote patient monitoring, elderly care, digital therapy, managing fatigue risks, and corporate well-being programs.

Benefits of Samsung Health Sensor SDK

Reduced Battery Consumption

Samsung Health Sensor SDK's accelerometer data, PPG data, and heart rate data are all received as a continuous event. The SDK's continuous tracker 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 data are provided as raw data by Samsung Health Sensor SDK. This is very helpful for developers when they conduct various analyses and more in-depth research with their 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 Samsung Health Sensor SDK, your watch application can easily measure these data.
