MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202531092303 A) filed by Narula Institute Of Technology, Kolkata, West Bengal, on Sept. 25, 2025, for 'wearable system for respiratory assessment using nonlinear system modelling.'
Inventor(s) include Dr. Moupali Roy; and Arpita Barman Santra.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a wearable system for real-time respiratory assessment that utilizes nonlinear system modeling to capture and analyze respiratory mechanics more accurately than conventional linear-based methods. The system comprises a compact array of biomedical sensors-including pressure, flow, and motion sensors-integrated into a wearable form factor such as a chest strap or vest. The sensor data is processed through an embedded computing unit implementing nonlinear identification algorithms (e.g., Hammerstein-Wiener, NARX models) to dynamically estimate respiratory parameters such as compliance, resistance, and airflow variability under different physiological conditions. The wearable device supports wireless communication for remote monitoring and features an intuitive user interface for clinicians or users. Unlike traditional spirometers or wearable trackers that assume a linear breathing pattern, this invention accounts for patient-specific nonlinearities, making it suitable for assessing complex respiratory conditions such as asthma, COPD, and post-COVID recovery. The system offers real-time alerts, trend visualization, and adaptive calibration, enabling continuous, intelligent respiratory health monitoring in both clinical and home-care settings."
