From the most perfect batteries it is of little use if they use toxic substances in their design. To become cyborgs, people will have to create energy sources , friendly to our bodies, and scientists already successfully draw inspiration for this from a “living electric power station” – the electric eel.

In the body of the eel, there are long strings of “electric cages” that communicate with each other so that the signal of the nervous system triggers the pumping of sodium ions in one direction, and the ions of potassium in the other.This movement creates an electric current with a total voltage of up to 600 V. In fact, everything is much more complicated, but the American scientists purposely simplified, and then copied this system.

Cells with fresh and salt water were placed on a dielectric flexible plastic substrate in a checkerboard pattern, which were separated by ion-selective membranes. In a quiet state, the cells did not touch each other, but when the substrate was bent, they came into contact and the ions began to pass through the membrane, generating a current. Technology, similar to reverse electrodialysis – controlling the salinity of water, the researchers produced electric current.

The experimental setup produced a voltage of 100 V, which, given the cost of its maintenance, does not yet allow us to speak of an acceptable level of efficiency. But the authors of the development are still satisfied – a prototype of an alternative energy generator has been created. And it is already easy to imagine an implant that will allow a person to start electric bundles from the fingers, simply straining his muscles and bending his arm. Or at least its low-power version to recharge other devices implanted in the body.
