Energy harvesting refers to the conversion of unused ambient energy into useful electrical energy. Ambient energy can be harvested from a variety of sources, such as light, electromagnetic wave, thermal, and mechanical vibrations. Whilst energy harvesting technologies have been explored for more than two decades as an alternative to conventional power sources for low-power applications, such as wearable electronics and wireless sensor networks, energy harvesting is now becoming a key enabling technology for a plethora of applications ranging from aerospace to automotive, from Internet of Things to building automation and structural health monitoring.
This collection aims to gather the latest advances on the development and application of energy harvesting technologies for self-powered systems. We will consider research in the fields of engineering, electronics, energy, materials science, chemistry, physics and computer science.
