Curved-crease origami face shields for infection control

Area of Science:

• Biomedical Engineering
• Materials Science
• Infection Control

Background:

• The COVID-19 pandemic has led to unprecedented global demand for personal protective equipment (PPE), particularly face shields.
• Existing face shield designs face challenges in meeting this demand, especially in low and middle-income countries.
• Effective face shields are crucial for protecting frontline workers from virus-containing fluid splashes and sprays.

Purpose of the Study:

• To present a simple, fast, and cost-effective manufacturing technique for face shields using curved-crease origami.
• To demonstrate the adaptability of the design across various manufacturing methods and contexts.
• To introduce a flexible physical-digital parametric design methodology for rapid design iteration.

Main Methods:

• Utilized curved-crease origami to transform flat plastic sheets into face shields.
• Explored diverse manufacturing approaches, from manual fabrication to industrial die-cutting and creasing.
• Developed a parametric design methodology for adaptable and customizable face shield variations.

Main Results:

• Successfully demonstrated a rapid and inexpensive method for producing infection control face shields.
• Confirmed the design's versatility, suitable for manual or high-volume production.
• The parametric design approach allows for easy adaptation to different ergonomic and protection needs.

Conclusions:

• The origami-based face shield design offers a scalable and adaptable solution to meet global PPE demands.
• This approach is particularly valuable for low and middle-income countries with limited manufacturing capabilities.
• The presented methodology facilitates rapid design refinement and customization for diverse applications in infection control.
