- Engineers developed a wearable wireless polygraph device to detect stress by monitoring multiple physiological signals.
- The device captures heart activity, breathing, sweat response, blood flow, and temperature for real-time stress assessment.
- It helps detect stress in non-verbal patients, monitor sleep disorders, mental health, and early medical complications.
- The wearable polygraph measures body responses to stress, not lies, and avoids needing chemical biomarkers from body fluids.
- It integrates sensors for mechanical, acoustic, thermal, and sweat gland signals, wirelessly transmitting data to smart devices.
- Machine learning analyzes stress patterns; the device weighs less than 8 grams and operates over 24 hours continuously.
- Validated in lie-detector tests, cognitive tasks, cold exposure, sleep studies, and emergency training scenarios.
- Future steps include clinical use in larger groups, personalizing detection, integrating into monitoring systems, and adding EEG capabilities.
