Abstract

Long term diagnostics and health monitoring of inaccessible sensors require strenuous power management or alternate power generation methods. Intraruminal devices can be powered with green energy using a microbial fuel cell (MFC). However, issues concerning poor steady-state power generation in anaerobic environments must be addressed. In this study, we propose a new type of structure of MFC for power generation in the rumen of cattle. Steady-state performance is evaluated with electrodes of 3 different materials. Using our proposed structure, the MFC's voltage drop in anaerobic environments is minimized, and each material electrode displayed a maximum power generation characteristic as follows: 0.4 µW/cm² for gold, 0.15 µW/cm² for platinum, and 0.002 µW/cm² for carbon.
