Abstract

Freshwater degradation due to human activities costs the United States over $2.2 billion annually, highlighting the urgent need for improved water quality monitoring methods. Traditional water sampling techniques are labor-intensive, time-consuming, and reliant on single-use plastics that contribute to environmental pollution. This research aims to address these issues by developing 3D-printed biodegradable sensor packaging for unmanned aerial vehicle (UAV)-assisted water sampling. By utilizing biodegradable materials, the research seeks to create an eco-friendly solution that ensures sensor durability while reducing negative environmental impact. The study will involve adjusting the packaging design to withstand UAV deployment by testing and improving the resistance of sensor packaging to water and other environmental factors and ensuring quick and safe degradation after use. 3D modeling using Shapr3D, 3D modeling software and the Prusa Slicer 2.9.0 app will guide the iterative design process. Rapid prototyping with Polyethylene Terephthalate Glycol (PETG) filament and will allow for iterative testing and refinement. The packaging prototypes will undergo rigorous testing, including drop tests and stability evaluations under various water conditions, to ensure their functionality and reliability. The final packaging design, fabricated with Butenediol Vinyl Alcohol Co-polymer (BVOH), is further evaluated for material solubility and environmental compatibility. This project aims to provide a cost-effective, sustainable approach to water quality monitoring by beginning the development of biodegradable sensor packaging to advance environmental protection efforts.
