SuperPatch REM PatchSham REM Patch
SuperPatch REM Patch: A drug-free, non-invasive vibrotactile (haptic) patch applied to the skin immediately prior to post-night-shift sleep and removed upon waking, intended to support recovery signals around sleep including sleep staging and autonomic metrics. Applied across 3-4 post-night-shift sleep episodes.
Sham REM Patch: A visually identical sham patch without vibrotactile technology, applied using the same timing, wear duration, and procedure as the active patch.

Inclusion Criteria:
* Adult doctors (≥18 years) working regular night shifts
* Able to provide informed consent and comply with remote study procedures
* Willing to wear a sleep-tracking wearable during the study period
* Willing to apply an adhesive study patch during designated post-shift sleep episodes
Exclusion Criteria:
* Known allergy/sensitivity to adhesives or significant dermatologic condition affecting patch placement
* Concurrent use of another device adhered to the body at the same site that could interfere with patch placement
* Any condition judged by investigators to make participation unsafe or data uninterpretable (e.g., acute illness impacting sleep)
