Abstract: In artificial vision parameter automating method, the system includes a sensory module, a communication module, a database, an image processing module, a learning module and a automating and storing module. The sensory module is configured to take images. The communication module is configured to be send the data obtained from the sensory module to the database. The database is configured to store the images received from the communication module. The image processing module is configured to convert a selected image from the database into a low-resolution phosphene image, to generate test images with various artificial vision parameters. The learning module is configured to extract important features from high-resolution training images, and to build various machine learning models competent at identifying visual stimuli from low-resolution phosphene images. The automating and storing module is configured to automatically select and store primary test data, based on the learning in the learning module.

Abstract: The present disclosure relates to a microneedle array-based electrode comprising organic photovoltaic substances, and an artificial retina device comprising the same, and the microneedle array-based electrode is coated with, as organic photovoltaic substances, a mixture of PCE10, which exhibits the highest absorbance in infrared rays, and ITIC, thereby exhibiting excellent photovoltaic efficiency and low phototoxicity. Further, since an artificial retina device comprising the electrode can adjust the generation of current only with light without any wire connecting the inside and outside of the eyeball, it is possible to restore nerve signals by stimulating the retina of a patient whose photoreceptor cells are damaged.
