Elastomers

Definition

Elastomers are a class of polymers characterized by their elastic properties, allowing them to stretch and return to their original shape. This unique flexibility and resilience make elastomers particularly useful in various applications, including neural interfaces where comfort, durability, and biocompatibility are essential. Their ability to mimic the mechanical properties of biological tissues makes them ideal for use in devices that interact directly with the nervous system.
