About this Research Topic
Power supply is one of the most fundamental and critical building blocks of nodes in wireless sensor networks (WSNs) to ensure pervasive and ubiquitous wireless communication. Most of today’s nodes in WSNs are powered by batteries. The batteries, as the power source, having a very limited capacity, need to be regularly replaced once they are depleted to allow nodes to continue operating. It has been recognised that the roll-out of more wide-spread and large-scale nodes in WSNs will be severely limited by the power supply. How to power the rapidly growing number of nodes in WSNs sustainably without using batteries is a grand challenge for the WSN applications in the 21st Century. Energy harvesting technologies can capture energy from its surrounding environment via a harvester and convert and store it into usable electric power via a power management circuit. As a result of this, nodes can be operated in a truly energy-autonomous manner. Sustainable power supply promised by energy harvesting technologies is urgently needed for the roll-out of more wide-spread and large-scale nodes in WSN applications. However, there are significant research challenges regarding the technology in terms of power output, bandwidth, reliability, efficiency, adaptation, configuration and deplorability prohibiting widespread industry take-up for deployments.
This Research topic will cover recent advances in energy harvesting technologies, including novel energy harvesting materials and devices, novel power management circuits and interfaces, and energy harvesting powered systems and applications, targeted toward technologies that are able to provide capability for energy harvesting powered systems, including wireless sensor nodes and networks. The aim is to collect the recent advances of energy harvesting technologies from materials, devices, power management applications. Through the collection of recent advances in the rapidly-evolving field of energy harvesting technologies, we aim to encourage the research and development from fundamental researches of energy harvesting materials to system integrations and applications, which will help to overcome the remaining technology challenges for large-scale applications.
