What are ways mechanical energy can be used to create electrical energy?

Question

besides rotational motion, like in generators or steam turbines

what OTHER kinds of motion are used to generate energy?

Answer 1

None really.

I guess you could consider pistons as linear motion but then it is converted into rotational energy for the dynamo to work.

Answer 2

In a dynamic microphone the movent of the diaphragm, which is connected to a maget and moves within a magnetised coil generates an electrical charge equal to the movement at the daiphragm - that electrical charge is sent through the cable and that is how we hear from a mic. Hence, magnetics in motion can generate a small current.

Answer 3

Not many because rotating bearings are so efficient.  Squeezing a piezo crystal will produce a voltage sufficient to make a spark.   Moving a magnet in a linear coil will produce enough electricity to sense the speed of movement of a reciprocating element.
