摘要

我们提出了一种0.25×0.25×0.3mm(~0.02mm3)的光动力微尘,用于视觉皮层刺激以恢复视力。最多1024个植入的微粒可以单独寻址。当光学供电时,完整的StiMote系统被证实是完全功能性的,并且用活体大鼠大脑在体内证实了皮层刺激。

A Wireless Neural Stimulator IC for Cortical Visual Prosthesis.

We propose a 0.25 × 0.25 × 0.3 mm (~0.02 mm3) optically powered mote for visual cortex stimulation to restore vision. Up to 1024 implanted motes can be individually addressed. The complete StiMote system was confirmed fully functional when optically powered and cortex stimulation was confirmed in-vivo with a live rat brain.
