Dead cell extracted-urine powered battery energy harvesting system

摘要

In this paper, the Dead Cell Extracted-Urine Powered Battery (DCE-UPB) Energy Harvesting system has been proposed. In DCE-UPB, energy is extracted by utilising trash primary cell and human liquid waste-urine. The DCE-UPB design consists of series-parallel combination of dead cell extracted- urine power single chambers. The single chamber cell consists of manganese as substrate along with the urine as electrolyte. The single cell of the proposed system also consists of two electrodes anode and cathode. The single cell of the proposed system has been tested and verified with various electrodes. The two suitable pair of electrodes have been selected i.e. copper/zinc and carbon rod/zinc. Each row consists of 12 cells connected in series and each cell produces an output of 0.85V and 1.2V corresponding to Cu-Zn and C-Zn electrodes respectively. The total output of the system is 10.61V for 145 hours and maximum current spike observed is 42mA. The power output is well enough to drive low power applications. In this proposed system, a LED has been used as low power load and driven by DCE-UPB.
