MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202521132488 A) filed by Ms. Kohia Katariya; and Ms. Shreya Patil, Pune, Maharashtra, on Dec. 27, 2025, for 'wearable device for muscle activity detection and assisted stimulation.'
Inventor(s) include Ms. Kohia Katariya; and Ms. Shreya Patil.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a wearable device (100) for muscle activity detection and assisted stimulation, comprising a surface electromyography (sEMG) electrode patch (103) for sensing muscle activity in a muscle affected by dystonia and a functional electrical stimulation (FES) electrode patch (104) for delivering electrical stimulation to an antagonist muscle to maintain balance and posture. The device includes circuitry for signal acquisition, amplification, filtering, digitization, and feature extraction, controlled by a processing unit (105) to enable real-time detection of muscle activation. Electrical stimulation pulses are synchronized with detected sEMG signals using timing control that temporarily suspends sensing during stimulation to minimize artifacts. The sensing and stimulation circuits are physically and electrically isolated, and safety is ensured through current limiting and an emergency shut-off switch (107). The device incorporates compact and flexible front and back patches (101, 102), medical-grade materials, wire interconnections (106), an operational status indicator (108), on-board SPI flash memory (SP1) for data logging, and wired or Bluetooth Low Energy communication. The device is adaptable for use on the neck, hand, forearm, or other body parts."
