Background:

Developing neural interfaces with both high stretchability and robust electrical properties is challenging.
Existing technologies often compromise mechanical flexibility for electrical performance.

Purpose of the Study:

To create a highly stretchable neural interface with concurrent robust electrical and mechanical properties.
To utilize a conducting polymer as the sole conductor for electrodes and leads.

Main Methods:

Fabrication of a neural interface using a conducting polymer film.
Characterization of the interface's electrical and mechanical properties under stretch.

Main Results:

The developed neural interface exhibits high stretchability and robust performance.
The conducting polymer film serves as the sole conductor for both electrodes and leads.
The electrode design leverages the large electroactive surface area of the conducting polymer, resulting in low impedance and high charge injection capacity.

Conclusions:

A novel conducting polymer-based neural interface offers a promising solution for demanding stretchable applications.
The material's properties enable effective neural signal recording and stimulation in a flexible format.
