Is energy harvesting a future for battery-free wireless sensor networks?

Interest in battery-free systems using capacitors and supercapacitors is growing, especially using piezoelectric technology. Energy harvesting has emerged as a promising avenue for addressing the constraints imposed by battery lifespan in wireless sensor networks (WSNs), paving the way for more sustainable and autonomous operations.

What is energy harvesting in wireless sensor networks?

Energy harvesting addresses the challenge of limited battery life in Wireless Sensor Networks (WSNs). This work systematically reviews peer-reviewed papers on the latest energy harvesting methods and mechanisms for WSNs. The review categorizes transducers, sources, and energy types to improve classification precision and understanding.

What is energy storage in he-WSN?

Energy storage Energy storage in HE-WSN is a critical aspect to ensure uninterrupted operation, especially during periods when the energy harvesting sources are unavailable due to the variable nature of these energy sources and, in many cases, the low levels of energy that can be collected.

What is energy harvesting for WSN?

Energy harvesting for WSN has been actively explored since at least 2003 joining the techniques to save energy to extend the WSN node's lifespan, referred to as mote. Its significance has grown in the last years expanding energy sources and the ability to extract it from the environment.
