MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202541117233 A) filed by Dr. G. Senbagavalli; Dr. Kinny Garg; Surabhi P; Varshini TN; PS Nikhil; and Tippeswamy H, Bangalore, Karnataka, on Nov. 26, 2025, for 'design and development of smart diaper system for dementia patients.'
Inventor(s) include Dr. G. Senbagavalli; Dr. Kinny Garg; Surabhi P; Varshini TN; PS Nikhil; and Tippeswamy H.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to the design and development of a wearable bladder monitoring system based on bioimpedance measurement for dementia and bedridden patients. The system employs surface electrodes placed near the bladder region to continuously measure impedance variations corresponding to bladder filling. The acquired analog signals are amplified, filtered, and processed using a microcontroller unit for real-time impedance interpretation. A threshold impedance value of approximately 1.9 kQ is defined to represent the full bladder condition. When this threshold is reached, the system triggers a wireless mobile notification to alert the caregiver or monitoring device. The invention operates in a continuous feedback loop, ensuring automatic detection without user intervention. The system is nun-invasive, low- power, and compact, suitable for long-term use. It provides an efficient, reliable, and cost-effective solution for real-time urinary monitoring in dependent patients."
