ActiGraph Device Features
ActiGraph’s suite of activity and sleep/wake monitors feature integrated Bluetooth® Smart technology and deliver a variety of advanced features, including:

Wear time sensor
An integrated wear time sensor uses capacitive touch technology to detect when an ActiGraph monitor has been worn for simplified compliance verification and data cleaning.

Mobile data uploads
Data collected by ActiGraph monitors can be uploaded to the web-based Study Admin Portal using a subject-facing companion mobile application for near real-time remote monitoring by the study team.

Proximity tagging
ActiGraph’s proximity tagging feature records the presence of other nearby devices, giving researchers the ability to track a subject’s interaction with their environment and/or other subjects.

Heart rate monitoring
ActiGraph devices deliver heart rate BPM and R-R intervals alongside physical activity measures when used with a compatible Bluetooth® wireless heart rate monitor.
