Obstructive Sleep Apnea (OSA) is a serious health condition characterized by repetitive airway collapses during sleep, which can lead to cardiovascular and metabolic complications if untreated. Positional OSA (POSA), a subtype triggered by specific sleeping positions, presents additional therapeutic challenges. This paper introduces a novel wearable device designed to treat POSA non-invasively. The system employs a microcontroller, inertial sensors, and a quiet piezoelectric pump to dynamically…
