Electrocytes that run end to end enable electric eels to create high-voltage shocks, and that structure is inspiring scientists to create biocompatible power sources for the human body. Researchers from the University of Michigan, the University of California at San Diego and the University of Fribourg in Switzerland have arrayed alternating hydrogel blobs of fresh and saltwater separated by ion-selective membranes to generate voltage by taking advantage of the differing salt concentrations.
