Scanning electron micrograph of the electrospun nanofibers on the small recording electrode. D. Scanning electron micrograph of the electrospun nanofibers covering the drug-loaded polypyrrole layer, which is deposited on the large drug release electrode. E. Zoom-in on the electrospun nanofibers covering the polypyrrole layer. F. Typical stress-strain curve resulting from the tensile test performed on the hybrid device.
