MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641049893 A) filed by Easwari Engineering College; Srm Institute Of Science And Technology, Ramapuram Campus, Chennai, Tamil Nadu, on April 20, for 'iot based sleep apnea detection and alaram system.'
Inventor(s) include Tamilmani M; Thirunavukarasu S; Shasheenth A; and Dr Chinthamani B.
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: "Obstructive sleep apnea is a potentially life-threatening sleep disorder marked by breathing disruptions during sleep, resulting in low oxygen levels and if left untreated it can cause a host of health problems including high blood pressure, heart problems and day time drowsiness. Hence for the early diagnosis and continuous monitoring of the abnormal breathing are need of the hour to avoid the long term health issues this paper proposes an IOT based sleep apnea detect and alarm system for continuous real time observation of the physiological parameters during sleep night the suggested system uses the wearable biomedical sensors like pulse oximeter and respiratory sensor to capture the physiological signals like SpO2 percentage, heart rate and breathing pattern. Sensor data acquired is fed to an ESP32 microcontroller for signal pre processing and parameter analysis using a cut off threshold conditions to detect the apnea events. The processed data is sent via Wi-Fi to a cloud service for remote monitoring and display of sleep data. Furthermore, an alarm system comprising a buzzer or indications is triggered in the case of detected abnormal breathing state or oxygen desaturation. The system is for continuous monitoring low power consumption and fast response and is therefore suitable for at home health care and remote patient monitoring. Empirical tests validate the capability of the designed method in establishing the sleep apnea incidents and providing prompt warning, which promotes the safety of patients and early medical treatment."
