The fibers consist of an array of metal electrodes connected to a semiconductor and are covered by an insulating polymer sheath. 这种纤维由一排连接在半导体上的金属电极组成,被聚合体绝缘层所覆盖。
And optical fiber is made of insulating material, will not arise the problem of waveform distortion caused by the radiation of the charged cable sheath. 而且光纤是由绝缘体材料制成,不会出现同轴电缆因外皮带电引起辐射导致波形失真的问题。
Another key factor is the insulating fatty sheath encasing neuron fibres, which affects the speed of electrical signals. 另一个关键的因素在于围绕神经纤维的隔离脂肪鞘,它能影响电信号的速度。
Although each neuron is coated in an insulating sheath, an impulse still creates a weak electric field outside the cell. 尽管每个神经元都包有绝缘鞘,但脉冲仍然在神经细胞外产生微弱的电场。
