Functional prototype
This year we decided to build a soil-based microbial fuel cell(sMFC) wireless sensor that can generate electricity whenever the genetically engineered Shewanella JG700. These are the components to build a sMFC wireless sensor
Components
Graphite fiber electraode
For our device to detect salicylic acid, we need to inoculate Shewanella on the anode. In our work, we ordered cathode and anode from Keego Technologies LLC, Stanford, USA. Soil was patted down in MFC up to 1 cm to make a smooth surface and anode was placed on the top of the soil, finally soil sample was added. The cathode was placed on the top of the soil. The garphite fiber electro allows the bacteria to make more contact with the electrode so that the bacteria can transfer much more electrons to the electrode than graphite electrode. We use titanium wire instead of copper wire since titanium wire since the corrosion resistance of tatinium wire is better than copper in soil and will do less harm to the envirenment.
External Power source
To deploy our device for a long time period, the wireless sensor network requires an autonomous electrical source in the wild that can recharge and store energy for extended periods of time. We used a solar portable charger to charge to power the wireless sensor. We would like to give a special thanks to Professor You-Yin Chen, a Lecturer in the Department of Biomedical Engineer, for his guidance. We integrated the battery into our device.
