A look at research on a skin‑attached ultrasound patch designed to noninvasively stimulate and monitor brain activity during REM sleep, explaining what readers can expect from the study and its implications for nonpharmacological sleep interventions.
Key Takeaways
- Skin‑attached bioadhesive ultrasound patch noninvasively shortened time to REM sleep in a small human study
- Patch both increased REM sleep duration and enabled real‑time electrophysiological monitoring during stimulation
- Nonpharmacological, noninvasive ultrasound stimulation shows potential for enhancing REM sleep without surgery or drugs
