Breakthrough in Sleep Technology: Wearable Ultrasound Patch Improves REM Sleep

A team of researchers from the University of Texas at Austin has made a groundbreaking discovery in sleep technology. They have developed a soft wearable patch called NEUSLeeP that can improve REM sleep in individuals without the need for medication or surgery.

The patch combines gentle ultrasound stimulation with electrodes that track brain activity in real-time. This allows the patch to target deep brain regions involved in sleep while simultaneously monitoring the brain’s response. This innovative technology opens up new possibilities for understanding sleep and treating sleep disorders in home settings.

The researchers tested the NEUSLeeP patch in a study involving 28 participants. The results, published in Nature Communications, showed that participants entered REM sleep 43 minutes sooner and remained in that stage for about 16 minutes longer. The benefits were observed in both healthy sleepers and participants experiencing some sleep difficulties.

Users also described the patch as comfortable and safe, and the study reported minimal adverse effects. The researchers are optimistic about the potential of this technology to support mood regulation and psychological resilience.

‘REM sleep is not just about dreaming – it’s about emotional reset and stress adaptation,’ explained Gregory Fonzo, assistant professor in the Dell Medical School’s Department of Psychiatry and Behavioral Sciences. ‘By enhancing REM, we may help people better cope with stress and improve their overall well-being.’

The team plans to conduct larger studies to verify the initial results and evaluate whether NEUSLeeP could help people with PTSD, depression, and chronic insomnia. They also see potential uses in home sleep monitoring, neuroscience research, and personalized sleep treatments.

‘Our vision is a future where patients with mental health disorders can optimize their sleep with a noninvasive and safe treatment,’ said Vincent Mysliwiec, M.D., a professor at UT Health San Antonio. ‘This technology could help millions of people get the restorative sleep they need.’

The researchers are collaborating with Discovery to Impact, UT’s commercialization unit, to move the technology toward the market. A patent application has also been filed for the device.

The team consists of Kai Wing ‘Kevin’ Tang, Benjamin Baird, William D. Moscoso-Barrera, Mengxia Yu, Mengmeng Yao, Jinmo Jeong, Ilya Pyatnitskiy, Anakaren Romero Lozano, Jiachen Wang, Ju-Chun Hsieh, Tony Sungjin Chae, Daniel Song, Julieta Garcia, Rithvik Mittapalli, Adam Bush, Wynn Legon, Vincent Mysliwiec, Gregory A. Fonzo, and Huiliang Wang.

Key Findings:

• Participants entered REM sleep 43 minutes sooner.
• Participants remained in REM sleep for about 16 minutes longer.
• The benefits were observed in both healthy sleepers and participants experiencing some sleep difficulties.
• Users described the patch as comfortable and safe.
• The study reported minimal adverse effects.

Future Directions:

The researchers plan to conduct larger studies to verify the initial results and evaluate whether NEUSLeeP could help people with PTSD, depression, and chronic insomnia. They also see potential uses in home sleep monitoring, neuroscience research, and personalized sleep treatments.

Conclusion:

The development of the NEUSLeeP patch represents a significant breakthrough in sleep technology. The potential of this technology to support mood regulation and psychological resilience is exciting and warrants further investigation.
