MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541125676 A) filed by P. S. R. Engineering College, Sivakasi, Tamil Nadu, on Dec. 12, 2025, for 'wearable asthma attack predictor.'
Inventor(s) include Dr. T. Senthil; Maheshwari A; and Keerthika A.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a system and method for pre symptomatic prediction of acute asthma attacks utilizing a multi modal wearable device. The system addresses the reactive nature of current asthma management by continuously monitoring subtle physiological changes indicative of respiratory stress. The core innovation lies in the Multi-Modal Sensor Fusion Algorithm, which correlates three distinct data streams: acoustic analysis (identifying high-frequency, sub-audible tracheal sounds or "micro-wheezes"), mechanical sensing (quantifying increased work of breathing via chest wall motion), and physiological data (detecting autonomic nervous system shifts via Heart Rate Variability or HRV). By establishing a personalized baseline and calculating a dynamic Attack Probability Score that anticipates airway constriction minutes before the user feels symptoms, the system enables proactive intervention with preventative medication, significantly improving patient safety and outcomes."
