Abstract

A nanofiber electrode may be provided. The nanofiber electrode may include a first nanofiber layer and a second nanofiber layer. The nanofiber electrode may further include one or more conductive feedlines sandwiched in between the first nanofiber layer and the second nanofiber layer. At least of the first nanofiber layer or the second nanofiber layer, when exposed to a liquid, may be configured to absorb the liquid and expand thereby changing a three-dimensional shape of the nanofiber electrode.
