MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202511013696 A) filed by Indian Institute Of Technology Delhi on February 18, 2025, for A Wearable Ultrasound System For Human Machine Interfaces.
Inventors include Mukherjee, Biswarup; and Kamatham, Anne Tryphosa.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The invention is a wearable ultrasound system designed for dynamic muscle activity measurement, offering high spatiotemporal resolution. It comprises an 8-channel transceiver system with a high-voltage pulser and an analog switch for pulse-echo operation. The receiver section includes a low noise amplifier, variable gain amplifier, and envelope detector, all managed by an STM32U575 microcontroller. This setup allows for real-time data acquisition and processing, transmitting digitized signals to an external device. The system's compact design makes it suitable for integration into biomechatronic devices like prosthetics. Figures illustrate the system's architecture, pulse-echo setup, signal processing stages, M-mode data during gestures, and a confusion matrix for gesture classification, demonstrating high accuracy. This invention addresses limitations of traditional methods, providing a non-invasive, efficient solution for applications in prosthetics, rehabilitation, and gesture recognition, enhancing human-machine interaction.
