Energy autonomous eSkin

The operation of multiple components (from few sensors to millions of electronic devices) distributed along surface of an artificial skin will be a major challenge for next generation of prosthesis and robotics. In this regard, a compact, light-weight and wearable energy system, consisting of energy generators, energy storage devices and low power electronics, is highly needed. The latest discoveries with advanced materials (e.g. nanostructures, thin films, organic materials, etc.) have permitted the development of the lighter and wearable sensors, energy harvesters and energy storage devices. Moreover, new techniques to evade wired connection in robotics/prosthesis by using conformable energy generator and storage as well as wireless data/energy transmission have opened new technological era. The paper highlights the key challenges, critical design strategies, and most promising materials for the development of an energy-autonomous eSkin for robotics, prosthetics and wearable systems.
