MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641044134 A) filed by Saveetha Institute Of Medical And Technical Sciences, Chennai, Tamil Nadu, on April 7, for 'contactless emotion and distress detection system for non-verbal bedridden patients using mm wave radar sensors and artificial intelligence.'
Inventor(s) include Dr. Pavithra S; S. Sri Keerthana; and Deepak Nallaswamy Veeraiyan.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a contactless emotion and distress detection system designed to monitor non-verbal or immobilized bedridden patients in healthcare environments. The system operates on rechargeable lithium-ion batteries, ensuring portability and uninterrupted operation. It incorporates multiple millimeter-wave (mmWave) radar sensors positioned on the headboard and footboard of a patient bed to continuously detect micro-movements, respiration patteras, restlessness, and abnormal stillness without physical contact. An Arduino-based microcontroller integrated with an artificial intelligence and machine learning module processes radar data to differentiate nonnal physiological activity from behavioral pattems indicative of emotional or physiological distress such as pain, anxiety, agitation, or discomfort. The system provides real-time alerts through visual indicators, audible alarms, and wireless notification mechanisms. The headboard unit houses the processing and alert components within a protective enclosure, while the footboard unit operates independently and transmits sensor data wirelessly via a Bluetooth module. By enabling early, contactless detection of distress in non-verbal patients, the invention improves patient safety, enhances caregiver response, and reduces reliance on subjective manual observation."
