A Theoretical Framework for a Detachable Liquid-Based Nerve-Controlled Robotic Prosthetic Limb

This work presents a theoretical and conceptual framework for a detachable, liquid-based, nerve-controlled robotic prosthetic limb. The proposed system explores the use of ionic or conductive liquid interfaces to transmit motor signals from residual nerves to prosthetic actuators, aiming to reduce complexity and cost while maintaining functional motor control. The framework emphasizes affordability, modularity, and psychological comfort, with a detachable design that supports easy maintenance and replacement. By leveraging established nerve-to-muscle mapping techniques such as myoelectric control, targeted muscle reinnervation, and direct nerve interfaces, the concept builds upon existing neuroprosthetic research while introducing a novel signal-transmission approach. This work is intended for academic discussion and early-stage research exploration. It does not present experimental validation, clinical trials, or approved medical devices. Any real-world medical implementation would require extensive experimental testing, ethical approval, and regulatory clearance.
