Microbial fuel cell–based self-powered biosensor for environment monitoring in IoT cloud framework

摘要

Renewable energy sources are useful for sustainable monitoring, but still very limited today dueto various implementation constraints. Microbial fuel cells (MFCs) are considered a promisingrenewable power source for remote monitoring applications. They are used as wireless temperaturesensors and biosensors due to their ability in powering environmental sensors. MFCs canprovide ultralow and dynamic power, and hence, energy improvement is crucial for self-poweredbiosensors. Cloud computing–based IoT framework is proposed for environment monitoringusing MFC-based biosensors. This paper presents the electric energy harvesting from OryzaSativa plants with bacteria as the catalyst. It adopts the technology of MFC in the plants toextract the maximum energy. An effective power management with IoT cloud framework ispresented in this work to independently operate multiple MFCs to generate maximum power.Independently operated MFCs with electrically isolated electrodes have been utilized in thedesign of a suitable power management system. Cloud computing is utilized in this work to processthe data generated in continuous monitoring of environment. Experimental results showthat the proposed framework can achieve sustainable power for sensor nodes and achievesmaximum performance in environment monitoring using cloud-based IoT platform.
