Sustainflatable: Harvesting, Storing and Utilizing Ambient Energy for Pneumatic Morphing Interfaces

While the majority of pneumatic interfaces are powered and controlled by traditional electric pumps and valves, alternative sustainable energy-harnessing technology has been attracting attention. This paper presents a novel solution to this challenge with the development of the Sustainflatable system, a self-sustaining pneumatic system that can harvest renewable energy sources such as wind, water flow, moisture, and sunlight, convert the energy into compressed air, and store it for later use in a programmable and intelligent way. The system is completely electronic-free, incorporating customized energy harvesting pumps, storage units with variable volume-pressure characteristics, and tailored valves that operate autonomously. Additionally, the paper provides a design tool to guide the development of the system and includes several environmental applications to showcase its capabilities.
