So the way this works is, you take a microphone and you digitize the signal, and you put an electrode strip directly into the inner ear.

它们的工作原理就是， 拿一个话筒，将信号数字化，把电极条放入内耳。

Or, with the retinal implant, you take a camera and you digitize the signal, and then you plug an electrode grid directly into the optic nerve.

或者，通过视网膜植入，拿一个相机，将信号数字化，然后把电极网格直接插入视神经。
