功能性电刺激(FES)用于激活神经和肌肉，以恢复其在损伤或中风后的正常功能。考虑到电刺激不会直接激活神经组织，我们的目的是展示这种力量是如何在组织中分布的。为了估计不同组织(皮肤、脂肪、肌肉和骨骼)在自然多层体系中的能量分布，我们考虑了它们各自的几何和电学性质。使用基于有限元方法的组织模型进行模拟。我们给出了每一层的能量分布，并表明最大部分的能量损失在最上面的皮肤层，只有一小部分到达目标神经组织。
Functional Electrical Stimulation (FES) is used for activation of nerves and muscles in order to restore their normal functions after an injury or stroke. Taking into consideration that electrical stimulation does not directly activate neural tissues, our intention was to show how this power is distributed in the tissues. In order to estimate the power (energy) distribution in the natural multilayer system of different tissues (skin, fat, muscle, and bone) we considered their respective geometries and electrical properties. Simulation was performed using a tissue model based on a finite element method. We present the energy distribution for each layer, and show that the largest portion of the energy is lost in the top skin layer, and that only a fraction reaches the targeted neural tissue.
