And the stronger the compression on piezoelectric materials, the larger the voltage generated.

并且对压电材料的压缩越强，产生的电压就越大。

And this module generates all the important voltages by itself.

该模块自行生成所有重要电压。

So, we need a way to generate a voltage that gets charge to flow continuously, creating an electric current.

因此，我们需要一种产生电压的方法，使电荷不断流动，从而产生电流。
