This wearable patch could get you into REM sleep 43 minutes faster

Scientists at the University of Texas at Austin have created a skin patch called NEUSLeeP that may help users fall asleep in the rapid eye movement (REM) stage of sleep up to 43 minutes sooner, and stay in that phase for an additional 16 minutes. The patch integrates two technological elements not commonly found together in a wearable device: low-intensity ultrasound waves and electrodes designed to measure brain activity.

This combination allows the patch to stimulate specific deep brain regions associated with REM sleep while simultaneously tracking the brain's response in real time, all without invasive procedures. The study involved 28 participants who used the NEUSLeeP patch, and the results indicated that they entered REM sleep much earlier than their usual patterns, and experienced prolonged REM sleep.

This innovation has the potential to revolutionize the field of sleep medicine by providing a noninvasive method to monitor and influence sleep patterns. It also shows promise in treating sleep disorders, as it can monitor the brain's response to stress and potentially improve emotional well-being through REM sleep stimulation. The development of NEUSLeeP signifies a significant step forward in sleep research, offering a promising tool for both clinical and research settings.

The researchers are collaborating with Discovery to Impact, UT's commercialization office, to bring this technology to market, with the aim of making it accessible for at-home use and further sleep research.
