Electric Eel Inspires Biocompatible Power Source

Dec-14-17 A flexible power source inspired by the electric eel could open the door to biocompatible power sources for implanted devices.

The new power source was developed based on the understanding of the eel’s power generating cells, called electrocytes. The teams mimicked the eel’s ability by printing droplets of a hydrogel containing dissolved sodium and chloride on a plastic sheet, alternating with hydrogel droplets of pure water. Another sheet of plastic holding droplets of charge-selective hydrogel was then pressed on top of the first sheet, connecting the saline and pure-water droplet in a series to generate an electric current.
