This paper develops biomimetic scaffolds to mimic human subretinal debris in animal models, improving the accuracy of preclinical testing for subretinal prostheses.

The paper presents a retinal stimulation system using eye tracking and a VCSEL array to achieve high optical efficiency and a wide field of view.

This study shows that residual photoreceptors affect the response of a degenerate retina to electrical stimulation, with implications for improving subretinal prosthesis design.

This paper optimizes a 3D electrode design for a photovoltaic subretinal implant to improve visual acuity beyond current clinical devices.

The paper develops doped amorphous silicon resistors for photovoltaic retinal implants, enabling smaller pixel sizes and improved electric field contrast without reducing photoresponsivity.

This study upgrades a subretinal photovoltaic implant in rats, improving visual acuity from 100m to 28m pixels.

This paper accelerates multi-electrode array simulations using sparse and low-rank matrix techniques, achieving up to 133x speedup with minimal error.
