Electric Eel Power Could Fuel Future Implants
Electric eels generate power using stacked cells called electrocytes. MIT scientists created hydrogel-based bioelectric generators inspired by this design. Their 2024 prototype produces 110 microamperes using only body fluids. Human testing starts next year. This technology could eventually power pacemakers without batteries, eliminating replacement surgeries entirely. These self-sustaining power sources convert chemical energy from bodily fluids into electrical energy just like the specialized organs in electric eels.
