Wearable technology has seen substantial advances in recent years, mainly triggered by the need for noninvasive, non obtrusive ways to monitor physiological signals outside the lab, in ecological/naturalistic context. In this study,
the Zephyr HxMTM system, a wearable heart rate monitor, was used, in 12 volunteers during the Trier Social Stress Test (TSST). The main objective was to assess whether any HRV
metric enables the distinction of stressful moments in short time scales. Results show consistent differences between TSST
phases for the AVNN and the potential of enabling fine-grained evaluation of experienced stress in real-life scenarios.
