Abstract

The invention relates to a near-infrared super-vision flexible artificial retina. The artificial retina comprises a photo-thermal material for light absorption, a ferroelectric polymer material for electric signal output and a micro-nano-scale periodic dot matrix array obtained on the surface with a processing technology. The artificial retina has a micro-nano-scale periodic array structure, the photo-thermal material is used as a light absorber, meanwhile, an electric signal is generated in situ through light absorption, and the problem that the artificial retina responds to near-infrared light in a photo-thermal effect and pyroelectric response coupling mode is solved.

Description

technical field

[0001] The invention relates to an artificial retina, in particular to a near-infrared super vision flexible artificial retina and a manufacturing method thereof, belonging to the technical field of implantable bioelectronic devices. Background technique

[0002] Vision is one of the essential senses of human beings. Normally, the photosensitive wavelength band of the human visual nervous system is between 400-700nm, that is, the visible light band. For mammals, the photosensitive pigments in the retina fail to detect longer-wavelength light, such as near-infrared light, and bioelectronic devices can improve the photosensitive pigment's insufficient perception of infrared light.

[0003] The prior art includes various forms of retinal implants. According to the location of the retinal implant device, it can be divided into two types, one is the retinal prosthesis, which generally consists of implanted devices (electrode arrays, batteries and wireless antenn...
