Four programs across pulmonary, neural, and swallowing physiology — plus the data plane that connects them. Each addresses a documented clinical gap with a specific engineering approach.
Handheld pulmonary function instrument. Measures FEV1, FVC, FEV1/FVC, and peak expiratory flow against ATS/ERS acceptability criteria, scoring each maneuver against a learned per-user baseline. ESP32-S3 platform, differential-pressure flow sensing, replaceable mouthpiece.

Mastoid-worn physiologic patch under 18 grams. Two-channel EEG at TP9/TP10 fused with photoplethysmography, electrodermal activity, and skin temperature — a 12-dimension feature vector scored every 30 seconds.

Flexible anterior-neck patch for continuous swallowing analysis. Surface EMG and vibroacoustic fusion classify each swallow within two seconds on-device — normal, silent aspiration, overt aspiration, or non-swallow.

FHIR R4 clinical data infrastructure. Real-time ingestion from every MSTFA instrument into one canonical patient record, served through standard interfaces with full patient-controlled export.
