Wireless Patch Detects Stress Signs Linked to Deception

A wireless patch system measures physiological signals tied to stress that can appear during interviews. The device operates without wires and attaches to the skin.

The system records changes in heart rate, skin conductance, and breathing patterns. Researchers tested the patch on subjects answering questions designed to elicit truthful and deceptive responses.

The same hardware can track nighttime breathing irregularities in children. Data collected by the patch can be reviewed by clinicians for signs of disrupted sleep. The patch transmits readings to a nearby receiver for analysis. Developers stated the technology is intended for controlled settings such as medical evaluations.
