Wearable polygraph detects hidden stress

Small, flexible, wireless device gently adheres to the chest to measure multiple physiological signals at once. By tracking heart rate and rhythm, breathing rate and depth, sweat response, blood flow and temperature, device captures a whole-body ‘view’ of stress. Machine learning algorithms analyze patterns associated with stress in real time. Device could help clinicians detect stress and discomfort in babies, the elderly and critically ill or sedated patients who cannot communicate.
