High-channel intramuscular and intrafascicular electrodes for transradial osseointegrated prostheses

Psyonic Inc., a minority-owned small disadvantaged business based in San Diego, California, received a $2.635 million project grant from the Defense Health Agency (DHA) under the Military Medical Research and Development program (CFDA 12.420), awarded September 30, 2025, with a completion date of September 29, 2027. The award supports research and development of high-channel intramuscular and intrafascicular electrodes designed for transradial osseointegrated prostheses—advanced prosthetic devices that integrate directly with bone and neural tissue to provide enhanced sensory feedback and motor control for upper limb amputees.

Under this two-year performance period, Psyonic Inc. will leverage its expertise in multiarticulated prosthetic hand technology to develop sophisticated electrode systems that enable bidirectional neural communication between users and artificial limbs. This research aligns with the DHA's mission to deliver innovative medical solutions for military service members and the American public by advancing prosthetic technologies that improve functionality and quality of life for individuals with limb loss. The project represents a competitive award through the Military Medical Research and Development program, which emphasizes hypothesis-driven research addressing critical health challenges through a rigorous two-tier peer and programmatic review process.
