阵列电极是一种很有前途的技术，可能会使经皮电刺激（TES）向前迈进一步。电极尺寸和位置的动态适应有助于简化电刺激系统的使用并提高其临床疗效。然而，到目前为止，阵列电极是通过试验和错误来构建的，例如，目前还不清楚如何构建。阵列元件之间的间隙或电极-皮肤界面材料的电阻率影响电流分布。由有限元模型和神经模型组成的TES模型已被用于分析阵列电极间隙和凝胶渗透率对神经激活的影响。仿真结果表明，电极-皮肤界面层的电阻率应根据阵列单元之间的间隙大小进行调整。此外，为了保持较小的损耗，差距大小应小于3 mm。(C)2009年IPEM。由爱思唯尔有限公司出版。保留所有权利。
Array electrodes are a promising technology that is likely to bring transcutaneous electrical stimulation (TES) a step forward. The dynamic adaptation of electrode size and position helps to simplify the use of electrical stimulation systems and to increase their clinical efficacy. However, up to now array electrodes were built by trial and error and it is unclear how, for example. the gaps between the array elements or the resistivity of the electrode-skin interface material influence the current distribution. A TES model that comprises a finite element model and a nerve model has been used to analyze the influence of array electrode gaps and gel resistivities on nerve activation. Simulation results indicate that the resistivity of the electrode-skin interface layer should be adapted depending on the size of the gaps between the array elements Furthermore, the gap sizes should be smaller than 3 mm in order to keep losses small.
