Silicone elastomers

Definition

Silicone elastomers are a type of synthetic rubber made from silicon, oxygen, carbon, and hydrogen that possess excellent elasticity, flexibility, and temperature stability. These materials are particularly valuable in soft robotics due to their ability to mimic the behavior of biological tissues and provide soft actuators and sensors that can adapt to their environment. Their unique properties make them suitable for applications requiring compliance and stretchability, which are essential features in bio-inspired designs.
