Elastomers

Definition

Elastomers are a class of polymers characterized by their elastic properties, allowing them to stretch and return to their original shape. These materials are crucial in soft robotics because they can mimic natural movements and adapt to various environments, enabling the design of flexible and responsive robotic systems that interact safely with humans and other objects.
