Abstract: In electrically stimulating neural tissue it is important to prevent over stimulation and unbalanced stimulation, which would cause damage to the neural tissue, the electrode, or both. It is critical that neural tissue is not subjected to any direct current or alternating current above a safe threshold. Further, it is important to identify defective electrodes, as continued use may result in neural damage and further electrode damage. The present invention presents system and stimulator control mechanisms to prevent damage to neural tissue.

Abstract: Polymer materials are useful as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision, cochlear stimulation to create artificial hearing, and cortical stimulation, and many related purposes. The pressure applied against the retina, or other neural tissue, by an electrode array is critical. Too little pressure causes increased electrical resistance, along with electric field dispersion. Too much pressure may block blood flow. Common flexible circuit fabrication techniques generally require that a flexible circuit electrode array be made flat. Since neural tissue is almost never flat, a flat array will necessarily apply uneven pressure. Further, the edges of a flexible circuit polymer array may be sharp and cut the delicate neural tissue. It is advantageous that the array edges not contact tissue.
Abstract translation: 聚合物材料可用作神经刺激的电极阵列体。 它们特别有用于视网膜刺激以产生人造视觉，耳蜗刺激以产生人造听觉和皮质刺激以及许多相关目的。 通过电极阵列对视网膜或其他神经组织施加的压力是至关重要的。 太小的压力会导致电阻增加以及电场分散。 太大的压力可能会阻止血液流动。 通常的柔性电路制造技术通常需要使柔性电路电极阵列平坦。 由于神经组织几乎从不平坦，平面阵列必然会施加不均匀的压力。 此外，柔性电路聚合物阵列的边缘可以是尖锐的并切割精细的神经组织。 阵列边缘不接触组织是有利的。
