The skin of the electric eel has become the basis of the “living” energy generator for cyborgs of the future

From the most perfect batteries of little use, if their design uses toxic substances. To turn into cyborgs, people will have to create sources of energy friendly to our bodies. And scientists are already successfully drawing inspiration for this from a “living 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 motion 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.

On a dielectric flexible plastic substrate, cells with fresh and salt water were placed in a checkerboard pattern and 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.
