Environmental sensor nodes support services from environmental stewardship to national security and defense. Expansion of high density sensor networks has been inhibited by the poor availability and high cost of long-term power sources. Trophos Energy demonstrates its own wireless environmental sensor network, entitled BackyardNet™, powered by Terrestrial Microbial Fuel Cell (TMFC) technology. When used in conjunction with Trophos’ power management electronics, TMFCs offer the potential for robust, long-term power solutions that can service a variety of remote monitoring applications. This paper discusses the technical aspects of the BackyardNet™ demonstration and the assessed viability of TMFC technology as robust power sources for remote applications.
