The wires produce electricity when under mechanical stress, called the piezoelectric effect.

当在机械应力作用下导线产生电能，这被称之为压电效应。

Coasting reduces mechanical stress because you use the momentum you gain from building up speed to keep the car moving forward.

滑行减少了机械压力，因为你是利用由加速获得的动力使车前行。

These are materials which can translate electrical fields into mechanical stress, or vice versa.

这类物质可将电场和机械压力相互转换。

Piezoelectricity essentially refers to current that accumulates in certain solids in response to applied mechanical stress.

This finding raises the question: can a small diameter lead be sufficiently robust to perform reliably over years of biologic exposure and mechanical stress in the human body?
