2241-2249Present study consists of an innovative energy harvesting system for low power devices. This harvesting system uses ocean water/ river water, sea sand, bacteria’s in ocean water using Microbial Fuel Cell as a source for power generation. The energy harvesting system consists of Microbial Fuel Cell and a power management system. Performance analysis of MFC is carried using Stainless Steel as anode and Magnesium as a cathode with waste milk , waste vegetables, soil, red sand, sea water collected at shallow water, sea sand, etc. are the various source samples. MFC is able to achieve more than 1V. Power management system consists of Charge Pump, Super capacitor and Interleaved Boost Converter (IBC). The developed energy harvesting system results in generating 6.8 V which is the requirement of the load. Thus the designed energy harvesting system provides relentless and justifiable power supply for remote underwater sensing, surveillance devices including data collections. Simulation results of energy harvesting system are carried out using Linear Technology (LT) spice
