Providing a proper energy-supply is one of the main requirements in the development of any engineering activity design. In the development of microelectronic devices for production of smart dust - the telecommunication sensor self-adjusted network – an critical drawback is dimension and weight of the power supply. Biological materials, such as enzymes, cells and subcellular structures show high technological potentials to be applied as catalyst in biosensors, sensors self-providing energy, Biological Fuel Elements (BFE), etc. The combination of biological materials with carbon nanomaterials allows an increase in the overall performances of BTE and opens new opportunities in the microenergy field. In this paper the main attention is paid to the interaction between nanomaterials and bacteria cells, aimed to obtain high values of the electric energy generated by Microbial Biological Fuel Elements (MBFE). The data available on the occurrence of direct electron transport and the generation of electricity when using membrane fractions of Gluconobacter bateria combined with thermo-expanded graphite during the oxidation of ethanol; modification of fuel cells electrodes with multiwall carbon nanotubes leads to an increase in the power of the microbial fuel cells. |
