Measured impedance at 1 KHz in vivo for two weeks after implantation. The strip-shaped seven-segment electrode array was placed into the suprachoroidal space and reference electrode was placed on the surface of sclera. A strip-shaped electrode site was connected to the working electrode input, and the stimulating reference electrode served as the counter and reference electrode. 0 week means the day of implantation.
