A survey-Energy harvesting sources and techniques for internet of things devices

Internet of Things (IoT) is a broad platform where various technologies help everyday devices to become smarter, more informative, communicative and intelligent. IoT devices need batteries to be powered and the lifetime of batteries is limited. Due to which there is a huge demand for energy sources that are competent enough to power IoT devices. Energy harvesting, accumulating and converting surrounding energy into usable energy, has emerged as a strong alternative to power devices. This paper discusses the need for harvesting the energy that arose in IoT devices. The methodology of different architectures and technology used in energy harvesting systems can be improved by understanding the survey on energy harvesting sources and techniques. The paper compiled various energy harvesting sources and techniques in tabular form which will act as a major input for researchers prior art pursuing in this field. (c) 2020 Elsevier Ltd.
