David T. Farrell, Connor M. McCann, Antonio Elia Forte, Conor J. Walsh, Katia Bertoldi · Wiley · 2025
This research introduces a textile metamaterial that adapts its aerodynamic properties through a stretch-induced dimpling mechanism.
Plain English summary
Why this matters
Key findings
- Textile metamaterial can adapt its aerodynamic profile through a stretch-induced dimpling mechanism.
- The material can modulate drag force by up to 20% at specific wind speeds.
- Active control of aerodynamic properties is possible through controlled stretching.
- Wind-tunnel experiments validated the variable aerodynamic performance.
- Finite Element simulations helped identify optimal material architectures.
What's new
The introduction of a stretch-induced dimpling mechanism in textile metamaterials for variable aerodynamic control is a new approach.
Limitations
The abstract does not provide details on the scalability or practical implementation of the textile metamaterial in real-world applications.
Commercial context
The research is still in the laboratory phase, with no indication of commercial availability.
