MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541114090 A) filed by Sethu Institute Of Technology, Virudhunagar, Tamil Nadu, on Nov. 20, 2025, for 'smart contraction belt with safety airbags for maternal safety.'
Inventor(s) include S. M. Seeni Mohamed Aliar Maraikkayar; Dr. N. Mahalakshmi; M. Jayasri; S. Vishnu Priya; P. Sweatha; and S. Sasma.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The titled invention discloses a smart contraction belt which is a wearable biomedical device to monitor maternal and fetal health during labor. The device integrates multiple sensors, including a heart rate sensor (1) for continuous monitoring of fetal cardiac activity to detect signs of distress, a flex sensor (2) for measuring abdominal expansion and contraction due to uterine activity, and an MPUeOSO motion sensor (3) for tracking fetal movement and orientation. Data from these sensors is analysed in real-time by a microcontroller (4) to detect abnormal or high-risk contraction patterns. Upon identification of such patterns, the system triggers an integrated airbag (9) mechanism that provides gentle abdominal support to reduce the risk of uterine rupture or internal injury. Simultaneously, an automatic alert notification (6) is transmitted to healthcare providers via wireless communication, ensuring timely medical intervention. Local alerts are provided through a buzzer and LED indicators (7), while an LCD display (8) offers real-time feedback on system status, contraction activity, and fetal heart rate. The device is powered by a rechargeable battery (10) for continuous, portable, and intelligent monitoring to enhance the safety of both mother and fetus."
