WearME-Pro Phase II: Remote Use Usability and Longitudinal Validation Study (Patch Form Factor).

WearME-Pro is a wearable, non-invasive physiological monitoring platform with two identical sensor modules, a patient-facing mobile application, and an optional clinician dashboard. For longitudinal use, the sensor modules are inserted into an adhesive patch retainer intended for prolonged skin contact (target up to \~28 days continuous wear per retainer; patch replacement per IFU/study procedures). The patch remains on the skin continuously between scheduled sessions; the mobile app initiates daily recording windows (typically totaling \~30-180 minutes/day), and sensors remain in low-power mode outside those windows. In the longitudinal component, participants complete daily WearME-Pro sessions plus daily handheld spirometry to enable paired comparisons. A subset of participants may optionally wear an FDA-cleared ECG patch (Cardea SOLO) for 24-48 hours at Baseline and End of Study as an exploratory heart-rate reference. Participants also complete daily symptom reporting and periodic questionnaires, with check-ins per the protocol schedule.
