We propose a self-sustainable wireless sensor node capable to monitor both environmental data and flora health state, exploiting a Microbial Fuel Cell combined with a plant. This bio-electrochemical system is used both as a power generator to supply the wireless embedded electronics and as a biosensor for estimating the status of the plant. We demonstrate that the sub-milliwatt power provided by the fuel cell is enough for achieving an energy-neutral smart sensor that samples and sends data. Moreover, the rate of the harvested power is correlated with the health of the flora living in symbiosis with the bacteria colony. The proposed system has been conceived to address the needs of future smart agriculture applications, providing an unobtrusive and energy neutral monitoring system open to a broad range of applications, thanks to the bacteria species that populate almost any soil on Earth.

Abstract
We propose a self-sustainable wireless sensor node capable to monitor both environmental data and flora health state, exploiting a Microbial Fuel Cell combined with a plant. This bio-electrochemical system is used both as a power generator to supply the wireless embedded electronics and as a biosensor for estimating the status of the plant. We demonstrate that the sub-milliwatt power provided by the fuel cell is enough for achieving an energy-neutral smart sensor that samples and sends data. Moreover, the rate of the harvested power is correlated with the health of the flora living in symbiosis with the bacteria colony. The proposed system has been conceived to address the needs of future smart agriculture applications, providing an unobtrusive and energy neutral monitoring system open to a broad range of applications, thanks to the bacteria species that populate almost any soil on Earth.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
