The\u00a0old adage\u00a0“never let them see you sweat,” doesn’t apply in the electrical and computer engineering lab of Rose Faghih, assistant professor\u00a0of electrical and computer engineering in the University of Houston Cullen College of Engineering. In fact, Faghih seeks sweat, the kind that beads on your upper lip when you’re nervous – skin conductance response (SCR) as the change in sweat activity is scientifically called. It is through that measure that Faghih is reporting the ability to monitor stress and even help lower it.\u00a0<\/p>\n

To collect and study\u00a0these physiological signals of stress, Faghih’s\u00a0research team has built\u00a0a new\u00a0closed-loop\u00a0technology<\/a>\u00a0by placing two electrodes on smartwatch-type\u00a0wearables.\u00a0Once the signal for stress is detected, a reminder is sent through the smartwatch, for example, to listen to relaxing music to calm down.\u00a0Thus, the loop is closed as the detected stress launches\u00a0the\u00a0subtle suggestion.\u00a0<\/p>\n

“This study is one of the very first steps toward the ultimate goal of monitoring brain responses using wearable devices and closing the loop to keep a person’s stress state within a pleasant range,” reports Faghih in the journal\u00a0IEEE Xplore<\/i>.\u00a0\u00a0<\/p>\n

Electrodermal activity (i.e., the electrical conductivity of the skin) carries important information about the brain’s cognitive stress. Faghih uses signal processing techniques to track the hidden stress state and design an appropriate control algorithm for regulating the stress state and closing the loop. The results of the research illustrate the efficiency of the proposed approach and validate its feasibility of being implemented in real life.\u00a0\u00a0\u00a0<\/p>\n

“To the best of our knowledge, this research is one of the very first to relate the cognitive stress state to the changes in SCR events and design the control mechanism to close the loop in a real-time simulation system,” said UH doctoral student and lead study author\u00a0Fekri\u00a0Azgomi, who accomplished the task of closed-loop cognitive stress regulation in a simulation study based on experimental data.\u00a0\u00a0\u00a0<\/p>\n

Due to the increased ubiquity of wearable devices capable of measuring cognitive stress-related variables, the proposed architecture is an initial step toward treating cognitive disorders using non-invasive brain state decoding.\u00a0\u00a0\u00a0<\/p>\n

“The final results verify that the proposed architecture has great potential to be implemented in a wrist-worn wearable device and used in daily life,” said Faghih.\u00a0\u00a0<\/p>\n

Stress is a worldwide issue that can result in catastrophic health and financial complications. A recent Gallup poll found that more than one in three adults (35%) worldwide said they experienced stress during “a lot of the day yesterday.”\u00a0\u00a0\u00a0\n <\/p>\n\n
