UofM’s mDOT Center Debuts Wearable AI Technology to Track and Reverse the Health Impact of Mental Exhaustion

Breakthrough biometric models now support frontline healthcare workers through the CuesHub mobile app featured on Action News 5

A new wave of wearable technology developed at the University of Memphis is transforming how people monitor stress, exhaustion, and recovery in their daily lives. Researchers at the mHealth Center for Discovery, Optimization & Translation of Temporally-Precise Interventions (mDOT) have created advanced biometric AI models that power CuesHub, a mobile app designed to detect when the body is under strain from excessive mental load and to provide timely prompts to prevent mental exhaustion.

Using workload heart rate—a physiological measure to show the impact mental demand on your heart—the technology allows users to know when mental exhaustion begins to impact their health when it is still reversible. These AI-driven models predict when the current pace of work is likely to lead to exhaustion, helping individuals to take action before burnout takes hold.

This innovative tool is now being used by frontline healthcare workers in Memphis, a group whose daily responsibilities often place them at heightened risk for chronic stress and overexertion. By receiving personalized cues for rest and recovery, healthcare staff are gaining a clearer understanding of their mental load patterns and learning strategies to better sustain their energy and resilience.

The feature includes an interview with Dr. Santosh Kumar, Director of mDOT, who shares how the Center’s long-standing research in wearable sensing, digital biomarkers, and AI-driven health assessment is translating into practical, real-world applications. Dr. Kumar notes that the integration of mDOT’s research into commercial tools like CuesHub demonstrates the Center’s commitment to improving population health and advancing the science of precision well-being.

As wearable technology and artificial intelligence continue to evolve, mDOT’s contributions are positioning the University of Memphis as a national leader in the development of tools that enhance health, resilience, and everyday quality of life.
