BiosenseSignal React Native SDK Developer Portal ​

Welcome to the BiosenseSignal Developer Portal!

This portal provides information about the API and the steps required for integration with the BiosenseSignal SDK. The BiosenseSignal SDK utilizes PPG technology to compute health indicators either by capturing a short video stream from the user’s face or by analyzing data from external PPG devices.

What's New in This Version - SDK v5.5 ​

1. Fall Detection Using Polar Verity Sense ​

Supporting fall detection using Polar Verity Sense devices. For details see the Fall Detection Page.

2. Improved Accuracy of RRi-related Vital Signs using External Devices ​

The calculation of RRi-based vital signs is updated and the accuracy is improved for the following vital signs: SDNN, RMSSD, SD1, SD2, Stress Index, Stress Level.

3. Removing Enforcement of 20% Battery Level for External PPG Devices Measurements ​

The requirement to have battery level of at east 20% when taking measurements using external PPG device Polar Verity Sense is no longer valid. Measurements can be taken at any battery level of the phone and the external device. However, the phone must not be in 'Power Saving Mode' when taking the measurement

4. Updating Blood Pressure Model for External PPG Device Measurements ​

The Blood Pressure model for external PPG device measurements was updated. There is no change in the supported Blood Pressure range and its accuracy levels.

5. Showing Vital Sign Results When the Confidence Level is Low ​

The confidence level of a vital sign indicates the probability of accuracy of the measurement result for that vital sign. Since this version, the vital sign results are reported whenever the SDK can calculate a result, including when the confidence level is LOW. For more information, see the Confidence Level page.

Known Limitations ​

  • Instruct the user to wait for 3 minutes between face measurements to prevent device overheating.
  • Instruct the user to wait for 1 minute between external PPG device measurements to prevent device overheating.
  • Android devices with lower Geekbench 6.0 (single-core) benchmark scores might encounter inconsistency when using the SDK.
  • The SDK must have a valid internet connection on the first launch to obtain license information. If an issue occurs, instruct the user to check their network connection and recreate the SDK session.
  • Hemoglobin and Hemoglobin A1c are under research.
  • Polar pairing tips:
    • During the discovery process, some other Polar devices might appear in the device list as Polar Verity Sense. Instruct users to pair only with Polar Verity Sense devices.
    • If repeated connections to the same device fail, instruct the user to open the operating system Bluetooth settings, find the device, open its settings and disconnect the device. If the problem persists, the user should verify the official Polar Flow app successfully pairs with this device and follow the instructions on https://support.polar.com/en/support/pairing_polar_device_with_flow_app_fails_now_what.

Getting the SDK and a License Key ​

A valid license key is required to activate the SDK and take measurements. Please contact the support team for getting a valid license key.

Sample Application ​

BiosenseSignal has prepared a sample application that demonstrates the integration with the SDK. The purpose of this app is to facilitate the development process of a new application. It is highly recommended as a starting point for developers to familiarize themselves with the API. For more information, please refer to the Sample App page.
