Introducing a unique battery inspired by electric eels

Experts inspired by electric eels have created a soft, foldable battery that promises to power devices like future pacemakers.

The electric eel (also known as the electric eel) crawls along the muddy bottoms of ponds and streams in the Amazon and Orinoco river basins of South America. It can deliver a shock strong enough to knock a horse off its feet. Photo: @Bedtime Math.

Their power comes from cells called electrocytes that release electricity when the electric eel hunts prey or feels threatened. Photo: @ Mongabay.

Now, researchers are taking inspiration from this special creature to develop a new energy source that could power bioelectronic devices in the human body in the future, such as pacemakers, biosensors, or prosthetic organs, etc. Photo: @ ZooChat.

Max Shtein, a materials scientist at the University of Michigan, said the electric eel can synchronize the charging and discharging of thousands of electrocytes in its body at the same time. Photo: @ Britannica.

Max Shtein suggests that the electrocytes in the electric eel's body are large and flat, with hundreds of these electrocytes stacked horizontally. Because of the way they are stacked, the tiny individual voltages fired from those electrocytes add up to a significant electrical discharge. Photo: @Catalogue of Organisms.

So, another team of scientists led by Michael Meyer from the University of Fribourg tried to replicate this power mechanism of the electric eel, by creating about 2,500 electrocytes made from positively charged sodium gel, and chloride gel dissolved in a negatively charged water-based hydrogel.

They then printed electrophoretic cells made from positively charged sodium gel as a layer containing small nodes, and printed electrophoretic cells dissolved in a negatively charged water-based hydrogel as a layer containing small nodes. Photo: @Michael Meyer.

These small button cells come in a variety of colors, and are mounted on a long, zigzag plastic sheet with opposite positive and negative electrodes. Photo: @Michael Meyer.

When the plastic sheet was folded up and stacked, the alternating layers of positive and negative cells touched each other and produced a 110-volt shock – a pretty big shock, but still lower than what an electric eel would produce. Photo: @Michael Meyer.

The researchers hope they can increase the voltage of this system by making the cell thinner, which will lower the resistance. Photo: @Michael Meyer.
