Mono-material recyclable fluidic logic pumps for sustainable systems
Rice University engineers have developed recyclable mono-material pumps using soft fluidic logic technology, promising precise dosing and scalability for sustainability-focused applications.
Overview
Rice University's Bioengineering Department has spearheaded the development of mono-material recyclable fluidic logic pumps. These pumps utilize a revolutionary approach called soft fluidic logic, which replaces traditional electronic components with fluid-based systems. This innovation facilitates the creation of pumps composed entirely of polymers, offering a sustainable and recyclable solution. The pumps promise precise dosing, reliable operation, and compatibility with existing bottles, aligning with sustainability goals by enabling curbside recyclability and potential incorporation of recycled materials.
Technical specifications
Key features:
- Constructed entirely from polymers using soft fluidic logic technology
- Precise dosing capabilities: less than 0.5 mL for sprays and approximately 1 mL for creams/gels
- Leak-free operation during usage and transportation
- Scalable manufacturing via low-cost injection molding
- Adaptable design for reusability and incorporation of recycled resins
The pumps are designed to be both efficient and environmentally friendly, with applications in a variety of consumer products requiring precise fluid dispensing.
Technology readiness level
This technology is at Technology Readiness Level 5, having been validated through laboratory environments and planned for further prototyping and bench testing to ensure dosing accuracy, leak prevention, and material compatibility. The path to commercial deployment includes phases of iterative optimization, scale-up, and potential IP transfer, with the aim of achieving a market-ready product.
