Stress in daily life has become a significant issue due to health risks. Because many sources of stress are unavoidable, management of stress is critical. Recent wearable devices, detecting physiological signals such as electrodermal activity, have been developed for quantitative and practical stress management assessment. However, they rely on a rigid and bulky system that is uncomfortable to wear during daily activities and has significant motion artifact issues. Here, we introduce a wireless skin-conformal bioelectronic system that evaluates daily stress management. Ultrathin, stretchable circuit system incorporated with a silicone elastomer enables a soft lamination on the skin, providing portable, continuous monitoring of stress. Printed, biocompatible nanomembrane electrodes on a breathable silicone tape provide long-term wearability and skin compatibility, enabling seamless monitoring of galvanic skin response at home with daily activities. Demonstration of stress management practice with human subjects shows the effectiveness of stress alleviation with a promising, non-invasive, and portable wearable system.
