MUMBAI, India, Sept. 7 -- Intellectual Property India has published a patent application (202641064154 A) filed by Srm Institute Of Science And Technology Tiruchirappalli on May 21, 2026, for Real-Time Heartbeat Detection System Using Precision Operational Amplifier Filter.
Inventors include Venkatesh Cg; Dr Ramasamy V; and Milofer Ss.
The application for the patent was published on September 04, 2026, under issue no. 36/2026.
Abstract: A real-time heartbeat detection system is presented using infrared sensing and precision operational amplifier based signal conditioning. The system detects blood flow variations from the fingertip and converts them into electrical signals using a photodiode. These weak signals are amplified and filtered to remove noise and motion artifacts. The processed signal can be displayed directly or used to calculate Beats Per Minute (BPM). The proposed system offers a reliable, economical, portable, and non-invasive solution for continuous heart rate monitoring suitable for medical, fitness, and personal healthcare applications.
