The process occurs thanks to special single-celled dinoflagellate algae. This work is inspired by the bioluminescent waves that can often be seen on beaches during the summer months.

How does it work

An exciting feature of these materials is their simplicity; They do not require electronics or an external power source. We show how the power of nature can be used to convert mechanical impulses directly into light radiation,
– commented the study’s senior author, Shenqiang Tsai, professor of mechanical engineering and aerospace engineering.

The main components of the material are dinoflagellates and alginate, a seaweed-based polymer. These elements were mixed to create a solution and then run through a 3D printer, which printed various shapes.

When the material is compressed, stretched or bent, the dinoflagellates within them respond by emitting light. The stronger it is, the brighter it is. This reaction mimics what happens in the ocean; In this way, microorganisms repel predators.

To continue working, Dinoflagellates in the material only need periodic cycles of light and darkness.. They photosynthesize to produce energy in the light phase, which is then used to emit light in the dark phase.
