Oh right @Njord insisted I tell you, fedi, about this button. It's a big orange button (AC remote for scale) that toggles an extension cord's power on/off when pushed
So far so boring right? Well it had been acting up a bit so we opened it up to change the battery and... no battery?
It apparently uses the mechanical force of pushing the button (it requires a bit of a push!) to trigger a piezoelectric charge which is apparently enough to send a wireless signal to the receiver
Neat!

I got fed up with batteries in door bell button and the "bell" and unreliability (433 MHz).
Eventually I found a real wired pushbutton and BingBong inside box, though that used batteries. So I added a transformer to 8V AC at the fuse box, because the bing-bong real solenoid doesn't care about AC or DC. The bulb in the door bell button is across the switch, so in series & glows orange, thus long life.1950s technology, but 100% reliable.
No spying to Amazon.

@leonardof I'm not sure but @Njord might be able to tell you

We had kinda the opposite in our last house. The button-push was wired to a battery-powered bell box, but the builders had put the bell and the battery directly above a radiator, which meant that we had to change the batteries every six weeks or so, because batteries don't like heat. We eventually gave up on it and installed something mains-powered.

German CASO has several models of battery free kitchen scales (as an idea, maybe other brands are available locally):

(via the menu you can change region to UK - while selecting Benelux doesn't seem to work) -

You can receive free electrons off of glucose through enzymatic breakdown similar than the body does - although the body stores it chemically in ATP or others.
It is however currently no longterm solution since the enzymes break down over time.
