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.

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, Mechanically Flexible, 25μm-Thick, 65,536-Channel Subdural Surface Recording and Stimulating Microelectrode Array with Integrated Antennas. 一种具有集成天线的无线、机械柔性、厚25μm、65,536通道硬膜下表面记录和刺激微电极阵列。

This paper presents a fully wireless microelectrode array (MEA) system-on-chip (SoC) with 65,536 electrodes for non-penetrative cortical recording and stimulation, featuring a total sensing area of 6.8mm×7.4mm with a 26.5μm×29μm electrode pitch. Sensing, data telemetry, and powering are monolithically integrated on a single chip, which is made mechanically flexible to conform to the surface of the brain by substrate removal to a total thickness of 25μm allowing it to be contained entirely in the subdural space under the skull.

本文提出了一种全无线微电极阵列（MEA）片上系统（SoC），具有65,536个电极，用于非穿透性皮层记录和刺激，其总传感面积为6.8mm×7.4mm，电极间距为26.5μm×29μm。传感、数据遥测和供电都集成在一个芯片上，通过去除基板的总厚度为25μm，使其具有机械灵活性，以符合大脑表面，从而使其完全包含在头骨下的硬膜下空间中。
