Elastomers

Definition

Elastomers are a type of polymer that exhibit elastic properties, allowing them to stretch and return to their original shape when a force is applied and then removed. This unique characteristic makes them ideal for various applications in soft robotics and artificial life, as they can mimic biological movements and behaviors. Their flexibility and resilience enable the creation of soft actuators and structures that can adapt to changing environments or tasks.
