Energy Conversion Efficiency

Definition

Energy conversion efficiency is a measure of how effectively energy is transformed from one form to another, specifically evaluating the ratio of useful output energy to input energy. In nanofluidic devices designed for energy harvesting and conversion, this concept becomes crucial as it determines how well these devices can harness and convert energy from sources like thermal gradients or chemical reactions into usable power. A higher efficiency indicates better performance and less energy waste, which is essential in optimizing the functionality of nanofluidic systems.
