System and method for implantable muscle interface
Summary
The USPTO granted Patent US12594172B2 to Johns Hopkins University for an implantable human-machine interfacing system that captures electromyographic signals from muscles and provides sensory feedback through electrical stimulation. The system includes sensors, amplifiers, a transceiver for wireless transmission to an external decoder, and an implantable power source for neuromodulation. The patent covers applications in prosthetics and assistive devices.
What changed
The USPTO issued Patent US12594172B2 for an implantable muscle interface device invented by researchers at Johns Hopkins University. The patent covers a system with a substrate containing sensors and amplifiers that capture EMG signals from motor units, wireless transmission to an external decoder, and an implantable power source for electrical stimulation providing sensory feedback and neuromodulation. The technology has applications in advanced prosthetic limbs and human-machine interfaces.
For manufacturers and researchers developing muscle interface, neural prosthetics, or assistive device technologies, this patent establishes Johns Hopkins University's exclusive rights to this specific implementation of implantable EMG-based human-machine interfacing. Parties operating in this technology space should review their R&D activities and product development pipelines for potential patent infringement exposure and consider licensing discussions with the university.

Abstract
An implantable human-machine interfacing system is disclosed that includes an implantable muscle interface device including a substrate including a first plurality of sensors and a second plurality of amplifiers that capture and amplify, respectively, electromyographic (EMG) signals arising from motor units under control of neural signals representative of volitional limb movements; and a transceiver device connected to the first plurality of sensors that wirelessly transmits signals to an external decoder that produces decoded signals that discriminate motor signals representative of movements of the motor units, wherein the substrate at least partially surrounds a muscle from which the EMG signals arise; and a receiver device that uses the decoded signals for interaction with an external system. The system includes a first plurality of electrodes and a second implantable power source that imparts electrical stimulation to the underlying tissues and sensory axons within for the purposes of sensory feedback and neuromodulation.
