Swiss researchers produce self-healing robotic skin

Swiss researchers have used a 3D printer to print a skin for a robot that can mend itself if damaged. The process is presented in a recently published study in the renowned journal “Nature Materials”.

Researchers at ETH Zurich have printed the skin for a robot’s gripping arm.

Living materials such as animal bones or plant stems are capable of self-healing, regenerating, adapting to the environment, and even making certain choices. The scientists at the Swiss Federal Institute of Technology in Zurich (ETHZ) wanted to take advantage of this property, they wrote in the study.

To do this, they used a 3D printer to print a three-dimensional lattice from a hydrogel loaded with the fungus Ganoderma lucidum. Similar to mold on food, the so-called mushroom mycelium, i.e. the root network of the mushrooms, populated this printed grid.
