MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641049905 A) filed by Easwari Engineering College; and Srm Institute Of Science And Technology, Ramapuram Campus, Chennai, Tamil Nadu, on April 20, for 'non-invasive diagnosis and therapy for sleep paralysis and other sleep disorders.'
Inventor(s) include Sharath Kumar S; Siddharth P A; Siddharth R; and Dr. K. Geetha.
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: "Sleep paralysis and related sleep disorders significantly affect physiological health and mental health, yet continuous monitoring and early intervention remain limited outside clinical environments. This work presents a non-invasive diagnosis and therapy system designed to detect and assist in reducing sleep paralysis episodes using wearable physiological sensing and embedded processing. The proposed system integrates photoplethysmography and galvanic skin resistance sensors with signal conditioning circuits and a microcontroller based architecture to monitor autonomic activity during sleep. Physiological signals are processed to identify abnormal patterns associated with sleep disturbances, after which an external therapeutic stimulation mechanism is activated to support recovery from distressing episodes. This design aims to achieve low cost hardware implementation, continuous monitoring, and portable operation suitable for real world usage. By combining physiological sensing, embedded control, and non-invasive intervention, the proposed framework aims to provide an accessible technological solution for improving sleep quality and managing sleep related disorders."
