Development and Evaluation of an Ambulatory Stress Monitor Based on Wearable Sensors

Medical Electronics Engineering

Monitoring stress levels has turn out to be a critical part of healthcare structures for physical and mental illnesses. Continuous stress tracking might help users better understand their stress patterns and offer physicians with greater dependable information for interventions. However, current stress tracking structures have did not acquire private information in an ordinary context. The contemporary country of sensor era permits us to broaden structures measuring the physiological signals, which replicate stress with the aid of using wearable devices. Therefore, we advise a stress tracking device that offers a goal each day healthcare primarily based totally on private physiological signals: electrocardiogram (ECG), photo plethysmogram (PPG), and galvanic skin response (GSR). We use the wearable devices, Shimmer3 ECG, Shimmer3 GSR and Empatica E4 Wristband, to monitor stress ubiquitously. We carry out managed stress experiments on sixteen members and the device effectively detects stress with 92.55% accuracy for 10-fold cross-validation and 83.61% accuracy for subject-wise cross-validation. In everyday settings, the device assesses stress with 82.12% accuracy. We also examine whether movement artifacts have an affect on stress assessment.
