它们经历温度变化时会像电池一样工作：给它们接上电极，它们就会产生电流。

These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current.

因为移动的电荷会产生电流，变化的磁通量会产生电压，新的设备会从电流中产生电压，像电阻一样，不过是以更加复杂、动态的方式。

Because moving charges make currents, and changing magnetic fluxes breed voltages, the new device would generate a voltage from a current rather like a resistor, but in a complex, dynamic way.

所以任何电流都会引起纤维振动，这时纤维就可以像麦克风或者话筒一样工作，当然这也取决于振动是否被记录或者放大。

So any electric current will then cause the fibers to vibrate. The fibers could act as a microphone or a speaker, depending on whether the vibrations were being recorded or amplified.

It's like electricity, you know, like the feeling of seeing that many people in the stadium

就像电流一样，那种在体育场看到超多人的感觉，
