Integrating BACtrack Skyn’s wearable alcohol monitoring device with Avicenna provides researchers with comprehensive transdermal alcohol concentration monitoring capabilities for behavioral and health research studies.
Supported BACtrack Skyn Metrics in Avicenna
Besides the common data fields, each record of BACtrack Skyn data in Avicenna includes the following fields:
- Transdermal Alcohol Concentration (TAC): Measures alcohol content through the skin in real-time in micrograms per liter (μg/L). This is the primary metric for detecting alcohol consumption events. Internally stored as
transdermal_alcohol_concentration. - Motion: Detects movement and activity levels in gravitational force units (g) to ensure the device is being worn properly and to correlate alcohol readings with physical activity. Internally stored as
motion. - Temperature: Monitors skin temperature in Celsius (°C) to ensure proper device contact and to detect potential device removal attempts. Internally stored as
temperature. - Skyn Device ID: Unique identifier for the specific BACtrack Skyn device. Internally stored as
skyn_device_id. - Firmware Version: Version of the device firmware for compatibility tracking. Internally stored as
firmware_version. - Mobile App Version: Version of the companion mobile application for data synchronization tracking. Internally stored as
mobile_app_version.
Data Collection Behavior
The BACtrack Skyn continuously monitors transdermal alcohol concentration through the skin, collecting data approximately every 20 seconds. It syncs with the BACtrack Skyn mobile app when the phone is in range via Bluetooth. See the next sections for more details.
Adding BACtrack Skyn As a Data Source
BACtrack Skyn data collection is implemented through File questions in surveys since there is no API to access the data.
To add BACtrack Skyn as a data source to your study, please contact our support team. Please provide the following information to the Avicenna support team:
- Activity ID containing the File question
- File question ID within that activity
Monitoring and Exporting BACtrack Skyn Data
You can export and download the collected BACtrack Skyn data using the Data Export page.
BACtrack Skyn Data Source in Participant App
- Participants need to install the BACtrack Skyn mobile app from the Apple App Store to sync their data with the BACtrack Skyn device.
- Researchers export the data from the BACtrack Skyn from their BACtrack Skyn dashboard as a CSV file. The dashboard’s access will be granted by the BACtrack Skyn team.
- Researchers upload the exported CSV file through the designated File question in the survey using a researcher-responded survey.
- Data is automatically processed and integrated into your study dataset.
