Ameliorated Urine Powered Battery (AUPB) for low power applications

In this paper, the ameliorated urine powered battery (AUPB) has been delineated and proposed for low power applications. In AUPB, the human urine has been deployed as a source of energy extrication. The natural neat human urine accompanying polyurethane sponge has been utilized as an electrolyte in the design. The proffered AUPB encompasses of hybrid (series and parallel) connection of small single chamber urine powered cells. In urine powered cells, the electrodes have been dipped in electrolyte and the potential across the electrode s has been appraised. In AUPB design, the intent is to exalt the electrical output of Urine Powered Battery by automating the system that is by gushing fresh urine into the system and sluicing out the exhausted urine from the system. It has been clinched that the best concoction of electrode materials (cathode-anode) is Cu-Zn which when enriched with urine and polyurethane sponge steers to augmented electrical output voltage and current. The single urine powered cell (UPC) is capable of providing the output voltage and current of 0.80V and 3.8mA. The AUPB comprising of 80 UPC's after employing LTC3388-3 has been proposed capable of generating the output voltage of 5.01V and current of 61.3mA which can be deployed for low power applications.
