摘要

神经组织的无线刺激可以使许多新兴的神经假体设计成为可能,并消除与经皮导线和连接器相关的问题。本实验室开发了一种用于慢性植入的16通道无线浮动微电极阵列(WFMA)。在这里,我们报告了它在体内实验中的首次使用,使用大鼠坐骨神经模型。在植入4只动物体内的两个WFMA装置的电极上测定了刺激电流和相关的肌肉运动。

In-vivo tests of a 16-channel implantable wireless neural stimulator
Wireless stimulation of neural tissue could enable many emerging neural prosthesis designs, and eliminate problems associated with percutaneous wires and connectors. Our laboratory has developed a 16-channel wireless floating microelectrode array (WFMA) for chronic implantation. Here, we report on its first use within in-vivo experiments, using a rat sciatic nerve model. Stimulus currents and associated muscular movements were determined for electrodes of two WFMA devices implanted into four animal subjects.
