Options for briefly powering Arduino + sensor using human force (button push?)

Using Arduino Project Guidance
1

Hi,

The idea is to have some sort of button which provides power from sustained pressure, with enough voltage to power up an Arduino and run a sensor reading, maybe writing to a e-ink display.

Does a button like this or anything similar that provides power from human input exist? I found some stuff about piezo buttons (piezo question, similar quora) but I don't think they generate enough consistent power...

Hand crank is one option, any others?

I realize using a battery would be much easier, but the project is about human power.

Thanks!

Google hand electric generator.

Ah yeah forgot to mention I came across hand crank generators too, but I don't like the ergonomics of having to crank. I was hoping there was some other way using just pressure from pushing a button or something, but this is a good backup option. thanks

If what you are saying was true, then adding a 2 ton weight to a component like this would make a perpetual motion machine. :thinking:

Well I'm imagining the button would slowly depress until it bottomed out at which point no more power.
but the perpetual motion machine isn't a bad idea I'll look into that too :wink: \s

...is potential energy, which can't ever generate power. Basic physics. Static forces in equilibrium don't require any energy input, and don't generate any energy output.
