Abstract
The spectacular growth of networks of intercommunicating sensing nodes has generated a request for alternate, renewable power sources. Thermoelectric generators (TEGs), either conventional or integrated, are possible candidates. This paper analyzes the usability of TEGs as alternate power sources for wireless sensor network. It is shown how TEGs meet power requirements of low-power sensing nodes and how they outperform batteries as of the installation costs. Factors still hampering TEG wider use are also reviewed and commented upon, and an outlook at specific applications where TEGs might be rapidly deployed is provided.
Highlights
In 2006 devices autonomously exchanging information were reported to have outnumbered humans connected to Internet worldwide [1]
Thermoelectric generators (TEGs) may play a relevant role, whenever temperature differences are available at deployment sites
As further discussed in the subsection, efficiency predicted by equation (2) neglects thermal contact resistances, which scale down the effective temperature difference applied to the thermoelectric legs
Summary
Commons Attribution 3.0 alternate, renewable power sources. Thermoelectric generators (TEGs), either conventional or licence. This paper analyzes the usability of TEGs as alternate power. Any further distribution of this work must maintain sources for wireless sensor network. It is shown how TEGs meet power requirements of low-power attribution to the author(s) and the title of sensing nodes and how they outperform batteries as of the installation costs. Factors still hampering the work, journal citation TEG wider use are reviewed and commented upon, and an outlook at specific applications where and DOI. TEGs might be rapidly deployed is provided
