How Sea Stars Build Materials That Can See

How sea stars build materials that can see

While studying how sea stars create lightweight, strong skeletons, my team at Penn Engineering discovered hidden lens-like structures that guide light. This accidental finding reveals how nature combines mechanical support with optical sensing in a single material system. We believe these biological principles can inspire future engineered materials that protect and monitor their environment simultaneously.

"In nature, one structure often serves many purposes because materials are expensive for organisms to make."
