An Iontronic Reservoir for Highly Robust Neuromorphic Prosthesis

Neuromorphic prosthetic devices are critical for bridging the gap between artificial machines and biological neural systems, yet conventional devices suffer from poor environmental adaptability and signal stability in complex human tissue environments. This study develops a novel iontronic reservoir-based neuromorphic prosthesis that simulates the signal transmission characteristics of biological nerve tissues. Benefiting from ion migration regulation mechanism, the device exhibits excellent robustness against temperature fluctuations, mechanical deformation and biofluid interference. It can stably capture and decode weak neural electrical signals, realizing high-precision man-machine interaction for limb movement control. The innovative iontronic structure breaks through the performance bottleneck of traditional electronic prostheses, providing a new technical route for the development of high-stability, bionic intelligent rehabilitation medical devices.
