Background:

Artificial implants are increasingly interfacing with human neurons for limb, brain, and retinal applications.
Current retinal implants face limitations in light transmission and neuron stimulation efficiency.

Purpose of the Study:

To propose and simulate bio-inspired fractal electrodes for enhanced neuronal stimulation in retinal implants.
To investigate the potential of fractal geometry to improve light transmission and neuron proximity.

Main Methods:

Simulations were conducted to compare the electrical field stimulation of fractal electrodes versus conventional Euclidean electrodes.
The study focused on a multifunctional electrode integrating a photodiode for light capture and neuron stimulation.

Main Results:

Fractal electrodes demonstrated a significant enhancement in neuronal stimulation compared to Euclidean electrodes.
Over 50% less electrode voltage was required for fractal electrodes to stimulate neighboring neurons.
A single diode configuration is feasible for fractal electrodes, unlike the three diodes needed for Euclidean electrodes.

Conclusions:

Bio-inspired fractal electrode geometry offers a promising approach to improve the efficacy of retinal implants.
These enhanced electrodes could lead to significant improvements in visual acuity, enabling patients to navigate environments more effectively.
