We implemented a light-sensing function on CMOS-based multi-chip stimulator for retinal prosthesis. Using the light-sensing circuitry attached to each stimulation electrode, the flexible multi-chip stimulator is capable of image-based patterned stimulation. We verified the function of the light-controlled decision based on the light intensity measured just beside the stimulation site. We also experimentally demonstrated in vivo retinal stimulation on rabbit's retina with light-controlled decision. The result of the present work is a simplified demonstration for the concept of retinal prosthesis with on-site imaging.
我们在基于CMOS的用于视网膜假体的多芯片刺激器上实现了光感测功能。通过将光感测电路连接到每个刺激电极，这种柔性多芯片刺激器能够进行基于图像的图案化刺激。我们基于在刺激部位旁边测得的光强度验证了光控决策功能。我们还通过光控决策在兔子视网膜上进行了体内视网膜刺激实验演示。本工作的结果是对具有现场成像功能的视网膜假体概念的简化演示。
