Novel MicroPower Source for Insect Based Sensor and Communication Platforms

Our objective is to develop a novel micropower source to be integrated with a microsensor, and communication chip on an insect, delivering a state-of-the-art unmanned chemical detection device. The biological fuel cell (Bio-FC) power source 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. During Phase I, we demonstrated power densities >150 µW/cm2 from two different insect species and also tested commercially available chemical sensors. Additionally, we selected the optimal insect species and investigated methods for artificial stimulation. In Phase II, we will optimize the Bio-FC to provide maximum power density while also being miniaturized and designed for integration with insect. Additionally the microsensor, microprocessor, and neuralstimulators will be designed. Subsequently, a fully-integrated prototype will be developed and mounted on the insect to provide proof-of-concept demonstration of an insect cyborg for unmanned detection of dangerous chemicals. A multi-disciplinary team with proven expertise in biomicrosystems, bioelectrochemistry, and insect physiology has been assembled to accomplish these goals.
