Background:

Implantable neural electrodes offer high-resolution neural recording but face challenges with chronic stability due to mechanical mismatch with brain tissue.
This mismatch can cause inflammation and signal degradation, limiting long-term applications in neuroscience research.

Purpose of the Study:

To review recent advancements in optimizing neural electrode-tissue interfaces for improved chronic stability and reduced inflammatory responses.
To explore novel materials, structures, and coatings for next-generation neural interfaces.

Main Methods:

Review of current literature on advanced electrode materials, including graphene and carbon nanotube fibers.
Analysis of flexible electrode structures, nano-coatings, and hydrogel-based interfaces.
Evaluation of electrochemical performance (impedance, charge injection limit) and recording stability (signal-to-noise ratio, neuron loss).

Main Results:

Graphene and CNT fiber-based electrodes show promise for enhanced neural interfacing.
Flexible electrode designs, nano-coatings, and hydrogels effectively mitigate inflammatory responses.
Optimized interfaces demonstrate improved long-term stability and biosignal recording capabilities.

Conclusions:

Recent developments in materials, structures, and coatings significantly enhance the performance and biocompatibility of neural electrodes.
These optimized neural interfaces are crucial for advancing long-term neural recording and modulation in neuroscience.
