Eel’s Electricity For Powering Implants

Artificial versions of the eel’s electricity generating cells can be used as a power source for medical implants and other tiny devices, suggests a study.

The paper, according to NIST engineer David LaVan, says that there are at least seven different types of electrical channels in eels, each with several possible variables to tweak, such as their density in the membrane.
