MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050189 A) filed by Rns Institute Of Technology; Jyotsna Nagalikar; Kaustubha K; J V Benakasree; and Dr. Akshay Arjun, Bengaluru, Karnataka, on April 20, for 'a wearable antenatal monitoring system and method for maternal-fetal health assessment with sensor fusion and edge-based risk prediction.'
Inventor(s) include Jyotsna Nagalikar; Kaustubha K; J V Benakasree; and Dr. Akshay Arjun.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a wearable antenatal monitoring system for continuous maternal-fetal assessment in low-resource settings. The system comprises a flexible patch configured for attachment to the maternal abdomen, integrating a photoplethysmographic (PPG) sensor, an acoustic transducer, and a temperature sensor. A processing unit acquires physiological signals and determines maternal cardiac timing from the PPG signal, which is used as a reference to suppress maternal cardiac components from the acquired vibroacoustic signal, thereby enabling extraction of fetal cardiac events and computation of fetal heart rate. A feature set including fetal and maternal physiological parameters is processed using a machine learning model executed locally on the device to generate a risk score and classify antenatal risk into predefined categories. The system further comprises a wireless communication module configured to transmit alerts to an external device via cellular communication without requiring internet connectivity. The invention enables low-cost, continuous, and real-time antenatal monitoring with on-device intelligence and remote alerting suitable for deployment in primary healthcare environments."
