Iontronics 

Charge movement implies energy and information transport and occurs at the core of many natural and technological processes. For example, the brain stores our memories and performs sophisticated computations using electrokinetic flows, electrostatic potentials, and polarization. Other examples are found in biomedical devices that sense biochemical signals through ionic and electronic currents, or batteries that store electric energy by moving ions and electrons between different media. In biological systems, ions transport charge through ionic channels, proteins, and membranes. Conversely, human technologies primarily employ electrons to transport charge in metals, semiconductors, and polymeric materials. Even though our society has achieved tremendous progress in information and energy processing, current technologies can not compete with natural processes regarding energy efficiency and information volume. To advance human technologies' boundaries, scientists combine ionic and electronic flows to design machines that perform advanced functionalities. This research lies at the intersection of materials science, solid-state physics, and electrochemistry and is encompassed in an emerging field known as Iontronics.
