The TOLIFE sensor kit, used in Clinical Study A (an observational prospective cohort study), gathers data on symptoms, performance, electrophysiologic signals, and environmental variables to estimate the health status of COPD patients. The kit includes a WiFi router, smartwatch, smartphone, smart shoes, smart mattress cover with a Bedroom Box Case (detecting light, temperature, humidity, and noise), and a mini-spirometer. Accessories include chargers, cables, and both paper and digital manuals. Data from the smart sensors are uploaded to the TOLIFE database via the WiFi connection.
