Wi-QuantumNet: Novel Passive Wi-Fi CSI Sensing for Aging and Underserved Independent Living

Overview

Each year, 82,000 Canadians die from heart disease and stroke, 40,000 experience out-of-hospital cardiac arrest, 100,000 are hospitalized due to falls, and 4.3 million live with undiagnosed sleep apnea. Yet the average patient receives less than 3 hours of clinical monitoring annually, leaving over 8,700 hours of health data invisible to physicians. This gap is especially dangerous for the 19% of Canadians in rural and Indigenous communities, where EMS wait times can exceed 14 minutes. Wi-QuantumNet transforms three $10 Wi-Fi devices placed anywhere in a room into a low-cost, contactless monitoring system capable of simultaneously tracking heart rate, breathing, emotions, sleep quality, fall risk, cognitive stress, and cardiac arrhythmia, without body contact, cameras, or monthly fees. Evaluated over 297 hours with four diverse participants, it achieved a heart rate error of 2.1 bpm, 94.4% fall detection, and 91.6% emotion recognition.
