MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202521084388 A) filed by Dimension Nxg Pvt. Ltd. on September 04, 2025, for Smart Eyewear For Monitoring Respiration Patterns.
Inventors include Abhishek Tomar; Purwa Rathi; Pankaj Raut; Abhijit Patil; and Yukti Suri.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: An eyewear-based respiratory monitoring system (2000) is disclosed comprising at least one MEMS ultrasonic transducer array (510) positioned in a nose-pad or nasal- bridge region and configured to interrogate spatially distinct respiratory target regions. The ultrasonic array (510) obtains an airflow-associated observable from a nasal airflow region and a time-of-flight based tissue-displacement observable from a facial tissue region. A thermal sensor (520) obtains temperature variations associated with inhalation and exhalation, while an inertial sensor (530) measures movement of the eyewear. A processor (600) determines reliability of one or more respiratory observables based on sensor operating conditions, including eyewear movement and thermal discrimination, and combines the observables according to their determined reliability. The arrangement enables multimodal respiratory monitoring while reducing errors caused by eyewear movement and degradation of individual sensing modalities.
