Fig. 10: Placement of wearable devices.

Example of a fully instrumented participant. The wearables are identified by the parameters they recorded: CBT (core body temperature), ECG (electrocardiography), ACT (actigraphy), and GPS (location tracking with a Global Positioning System device). Note: This figure includes an image of a participant taken with written consent; an opaque rectangular shape has been placed over the face to protect the individual’s identity.
