The knifefish Electrophorus electricus, better known as the electric eel, can generate electricity to stun its prey thanks to specialized organs that generate power via ion flux—no batteries required. The structure of these organs provided a jolt of inspiration to researchers led by Michael Mayer of the Adolphe Merkle Institute at the University of Fribourg, who wanted to create a soft power source. The electric eel’s organs contain thousands of . . .
