I have seen potatoes and apples being wired to generate electricity.

The key is whether this cost is controllable and whether it is cost-effective compared to batteries?

Your requirements are too high. It's just a popular science question.

Not only can metal pieces inserted into a lemon generate electricity, the human body can also generate electricity. Just go to the hospital and check the electrocardiogram to find out.

It is not lemons that can generate electricity, but the galvanic cell effect. Lemons only provide electrolyte and there is no energy loss themselves. Therefore, it is wrong to say "lemons can generate electricity" from the perspective of physical principles.

It's really interesting. Electricity is really amazing.

Eh~ is that so?

I learned a lot of useful knowledge.

Einthoven invented the earliest electrocardiogram measuring device in 1903, for which he was awarded the Nobel Prize in Physiology or Medicine in 1924.

Different metals have their own electrode potentials. As long as two different metals are placed in an "electrolyte" (such as various fruits, etc.), they can generate electromotive force, or voltage.

This is the principle~ Thumbs up~

The first electrocardiograph in 1903, 272 kg water-cooled, Einthoven, the Netherlands

It should be noted that at that time, even vacuum tubes had not been invented, let alone transistors. Without vacuum tubes, there would be no amplifiers, and the deflection of the coil in the electrocardiograph was entirely dependent on the electricity generated by the human body.

So wonderful! Thanks for sharing~

Fruits, plants, and soil can all generate electricity, such as:
