Our objective is to develop a novel micropower source, microsensor, and communication chip for integration with an insect, thereby delivering a state-of-the-art unmanned chemical detection device. The proposed biological fuel cell (Bio-FC) will leverage ongoing research at CFDRC and provide a compact/lightweight power supply, for mounting on numerous types of insects and producing necessary power without further custom development. This solution offers several advantages over the existing electromechanical methods; 50-100X higher power density, power-generation independent of insect species, and power generation in absence of insect motion. In Phase I, we will achieve an order-of-magnitude (OOM) improvement in power density (up to 100 µW/cm2) compared to electromechanical methods. Additionally, research will be performed to identify commercially available chemical sensors. Finally, the optimal insect species will be chosen, as related to potential energy generation and native signaling calls, in consultation with Dr. Richard Mankin at the USDA. Research will be performed into methods for artificially re-producing the signaling call. In Phase II, the Bio-FC prototype will be combined with a microsensor and the complete platform integrated with an insect to provide proof-of-concept demonstration. A multi-disciplinary team with proven expertise in biomicrosystems, bioelectrochemistry, and insect physiology has been assembled to accomplish these goals.
