Electric Eel Motivates Bio-Friendly Power Source

Researchers are always on the watch out for secure, more natural approaches to power tools that are inserted into our bodies. Certainly, who actually requires toxic battery components and replacement surgeries? One living entity that is pretty excellent at producing biocompatible energy (at least for itself) is the electric eel. And now, researchers have utilized the high-voltage species as an outline for a potential new self-charging tool that can someday power devices such as prosthetics, pacemakers, and even AR contact lenses.

Voltage is produced by electric eels via the lengthy masses of thin cells that extend end-on-end across their bodies. These cells, referred as electrocytes, generate electrical power by enabling sodium ions to run into one terminal and potassium ions out the other, simultaneously. The voltage produced by each cell is minute, but collectively, the masses within a single eel can produce almost 600 V.

To re-establish this result, the research teams from the University of Michigan, the University of California San Diego, and the University of Fribourg have focused on the dissimilarity in salinity between salt water and fresh water. They housed hydrogel, ion-enclosing droplets onto transparent plastic panels and divided them with ion-selective membranes.

Numerous droplets enclosing freshwater and salt were set in an alternating blueprint. When the researchers had all these gel sections make a connection with each other, they were capable of producing 100 V via what is called as reverse electrodialysis, where power is produced via differing concentration of salt in the water.

Though the eel stimulates the concurrent communication of its electrocytes with the use of a neurotransmitter known as acetylcholine as the directive sign, the researchers attained this by cautiously functioning a unique origami pattern—referred as Miura-ori fold—into the plastic sheet. This implied that on applying pressure to the sheet, it rapidly snapped mutually and the cells moved into accurately the right positions to generate the electrical energy.

The device, referred as an artificial electric organ by the team, is not in the same approximate as an eel in terms of yield, but the team does have some plans around how to enhance its efficacy. It points out the metabolic energy produced by ion dissimilarities in the stomach of an eel, or the mechanical muscle energy, as few of the likelihoods, but does mention that re-imitating these would be a huge challenge.

Mayer said, “The eels’ electric organs are extremely sophisticated, they are far superior at producing power than we’re. But the significant part for us was to reproduce the basics of what is occurring.”

He believes in the theory that no event which we see in our surrounding is a coincidence or happened randomly. Instead, they are just a consequence of combination of factors which surfaces in space-time domain. Therefore, we must be observant to understand the process responsible for triggering an event. So, he likes to stay observant and whatever he observes or learns from the surrounding, he loves to share to identify the missing links in his interpretation.
