The U.S. Navy seeks partners to mature and commercialize this patented, early-stage technology. Collaboration opportunities exist in rapidly-deployable tactical sensor-net frameworks, distributed antenna arrays, micro fuel cells, and meta-materials.
Small unmanned aerial vehicles (UAVs) (also known as micro air vehicles, or MAVs) are promising tools for a variety of military and commercial applications. Some small UAVs have flexible wings and are light weight, making them back packable and easy to deploy, but lack in extended communications and battery life. To enhance communications and battery life without sacrificing weight and deploy-ability, inventors at SSC Pacific have conceptualized a flexible wing that incorporates electronics, sensors, and fuel cells, and can self-erect upon receiving thermal stimuli.
The concept covers a wing made of a flexible dielectric substrate, providing surface area for flexible printed circuitry and micro fuel cell components. Flexible printed circuitry such as microstrip patch or printed antennas enhance transmitter/receiver and network capabilities with minimal added space and weight. Micro fuel cells have the potential of increasing battery life by 10 times compared to lithium-ion batteries. Bonded to the substrate is a layer of shape memory polymer, enabling the wing to self-erect when thermally stimulated. Ultimately, the inventors envision a low-cost, throw-away wing made of an expendable meta-material, effectively making the wing a replaceable battery and sensor component.
